EBSCO Open Dissertations

EBSCO Open Dissertations makes electronic theses and dissertations (ETDs) more accessible to researchers worldwide. The free portal is designed to benefit universities and their students and make ETDs more discoverable. 

Increasing Discovery & Usage of ETD Research

EBSCO Open Dissertations is a collaboration between EBSCO and BiblioLabs to increase traffic and discoverability of ETD research. You can join the movement and add your theses and dissertations to the database, making them freely available to researchers everywhere while increasing traffic to your institutional repository. 

EBSCO Open Dissertations extends the work started in 2014, when EBSCO and the H.W. Wilson Foundation created American Doctoral Dissertations which contained indexing from the H.W. Wilson print publication, Doctoral Dissertations Accepted by American Universities, 1933-1955. In 2015, the H.W. Wilson Foundation agreed to support the expansion of the scope of the American Doctoral Dissertations database to include records for dissertations and theses from 1955 to the present.

How Does EBSCO Open Dissertations Work?

Your ETD metadata is harvested via OAI and integrated into EBSCO’s platform, where pointers send traffic to your IR.

EBSCO integrates this data into their current subscriber environments and makes the data available on the open web via opendissertations.org .

The top list of academic search engines

1. Google Scholar

4. science.gov, 5. semantic scholar, 6. baidu scholar, get the most out of academic search engines, frequently asked questions about academic search engines, related articles.

Academic search engines have become the number one resource to turn to in order to find research papers and other scholarly sources. While classic academic databases like Web of Science and Scopus are locked behind paywalls, Google Scholar and others can be accessed free of charge. In order to help you get your research done fast, we have compiled the top list of free academic search engines.

Google Scholar is the clear number one when it comes to academic search engines. It's the power of Google searches applied to research papers and patents. It not only lets you find research papers for all academic disciplines for free but also often provides links to full-text PDF files.

Tips and tricks

• This Website Won't Work (Troubleshooting)
• Google Suite
• Search Engines
• Metadata Search & Web Directories
• Invisible/Dark Web
• Keyboard Shortcuts

You can use the same search strategies you use in your every day life to search the internet (you've been doing it for years!). You can also apply the advice in the Search Strategy, Advanced Search Techniques , and Find Articles tabs on the left to make you more effective. 

The tabs in this box highlight different areas of the internet you may want to consider in your search, beyond Kemp Library's databases - or if the assignment asks for a website beyond a newspaper or magazine, etc.

Don't forget to evaluate your websites - check out the Website tab on the left.  

If you run into a website where you can't navigate it easily or the search won't work, links are broken, etc. try going to a search engine (Google, Yahoo, Bing), and searching the name of the website and keywords of what you're looking for.  This is a workaround strategy.

You're having trouble finding information on the U.S. Census Bureau's website . No matter what you do, the pages you can find on poverty aren't right or are the wrong information. Go to Google.com (or whatever your search engine of choice is), type in "us census bureau poverty 2017 " and see what comes up.  You can get more specific or use different keywords or keyword types - like poverty and children, poverty threshold, poverty and hunger, etc.  Your results will all be from the Census Bureau's website so you can navigate it outside of the webpage's own navigation (see image below).  Try to use terms your search engine can find.

You know how to use Google, but do you know how to get to the advanced search in Google ? You can also edit your search settings in Google. There is a video at the bottom of the box on how Google works as well. 

Don't forget about Google Scholar or Google Books either.

You can access the Advanced Search and your Search Settings by clicking on Settings in the lower right-hand corner of Google.com .

The top ten search engines in the world as of 2022 are :

• Baidu  (Chinese)
• Yandex  (Russian)
• DuckDuckGo - if you're into your privacy, this is your search engine. They don't track your searches or information, they have browser extensions, and they have some other nice features you may be interested in. 
• Ecosia   - this helps finance planting trees and restoration projects through your searching. It's a partner of Bing
• InternetArchive - you can see how websites used to look, as well as access tons of freely available content.

We also recommend  Wolframalpha - searches formulas, computations, calculations, and more! This is not your normal search engine.

A great science search engine is Science Stack - Academic Search Engine .  This combines the search of Mendeley and PLoS and allows for data interaction in new and creative ways. Great for academic science searching. This also has Firefox extensions and add-ons.  

Metadata Search Engines use other search engines to perform a search - typically they search multiple search engines at once and aggregate the data into one result stream. Some of these are better than others, but it's up to you if you want to consider using them or not. A major con is that most aren't able to sift through the results properly so you get a lot of irrelevant results. What's available changes frequently, but you can find out more over at Wikipedia .  A couple examples are All4One, one of the first metasearch engines, and Metacrawler . You can also check out this article if you're interested in trying others.

Web Directories have two typical structures. One is hierarchical, which lead from general topics to more specific ones, and usually covers a broad range of topics. The other typically just lists sources in some sort of order, like alphabetical and covers resources on a specific topic like Game of Thrones fan theories.   The turnover rate on these can be high, but some stick around for a while. One that is a great resource for college students is the Directory of Open Access Journals.

Have you heard the term "the invisible web", "deep web", or "the dark web"? This refers to the internet that is below the surface of what most search engines, including Google, look at and access.  The fact is, most information in things like databases is completely inaccessible to search engines like Google or Bing.  Information that Google or Bing can see is called the " visible " web.

Information on the invisible or deep web can be accessed, but only through specific channels.  Anything that can't be found through a normal search engine like Google or Bing is considered the deep web. Why is this worth your time? The invisible web is estimated to be thousands of times larger and the visible web.

The dark web is a small part of the deep web that has been deliberately hidden and is generally inaccessible unless you're an IT wizard.

So how do you use the deep web?  Two of the broadest are the Virtual Library , despite the old school interface and Infoplease .  You can also check out these lists of deep web resources

• 10 Search Engines to Explore the Invisible Web
• The Ultimate Guide to the Invisible Web from OEDb (search tools at bottom)
• FindArticles : search articles from a variety of publications.
• Find Law : find information on legal issues organized by category.

BrightPlanet is a company who mines the deep web for various companies and reasons as their day job. They have a couple articles on their website as well that go into more detail about what the deep web is , the differences between the dark web and the deep web , and more! They've also written a white paper that you can get for free at the dark web link.

"Stopwords" or "stop words" are words that search engines, datagases , or any search interface may ignore, skip or may completely interrupt your search.  They may also affect how your results are listed (or in technical terms, "indexed"). These are usually common words such as " the, a, an, but ". You can see what a specific search engine or database, etc.'s stopwords are by Googling or otherwise looking up the name of the interface and " stopwords ".

Example: "what are Google stop words" or "what are EBSCOhost stop words"

You can see EBSCOhost's list of sample stop words and how they handle them here, or you can see the same information in the attached PDF.

EBSCO Open Dissertations

Search millions of electronic theses and dissertations (etds).

With EBSCO Open Dissertations, institutions and students are offered an innovative approach to driving additional traffic to ETDs in institutional repositories. Our goal is to help make their students’ theses and dissertations as widely visible and cited as possible.

This approach extends the work started in 2014, when EBSCO and the H.W. Wilson Foundation created American Doctoral Dissertations which contained indexing from the H.W. Wilson print publication, Doctoral Dissertations Accepted by American Universities, 1933-1955. In 2015, the H.W. Wilson Foundation agreed to support the expansion of the scope of the American Doctoral Dissertations database to include records for dissertations and theses from 1955 to the present.

Get involved in the EBSCO Open Dissertations project and make your electronic theses and dissertations freely available to researchers everywhere. Please contact Margaret Richter for more information.

Search Help

Get the most out of Google Scholar with some helpful tips on searches, email alerts, citation export, and more.

Finding recent papers

Your search results are normally sorted by relevance, not by date. To find newer articles, try the following options in the left sidebar:

• click "Since Year" to show only recently published papers, sorted by relevance;
• click "Sort by date" to show just the new additions, sorted by date;
• click the envelope icon to have new results periodically delivered by email.

Locating the full text of an article

Abstracts are freely available for most of the articles. Alas, reading the entire article may require a subscription. Here're a few things to try:

• click a library link, e.g., "FindIt@Harvard", to the right of the search result;
• click a link labeled [PDF] to the right of the search result;
• click "All versions" under the search result and check out the alternative sources;
• click "Related articles" or "Cited by" under the search result to explore similar articles.

If you're affiliated with a university, but don't see links such as "FindIt@Harvard", please check with your local library about the best way to access their online subscriptions. You may need to do search from a computer on campus, or to configure your browser to use a library proxy.

Getting better answers

If you're new to the subject, it may be helpful to pick up the terminology from secondary sources. E.g., a Wikipedia article for "overweight" might suggest a Scholar search for "pediatric hyperalimentation".

If the search results are too specific for your needs, check out what they're citing in their "References" sections. Referenced works are often more general in nature.

Similarly, if the search results are too basic for you, click "Cited by" to see newer papers that referenced them. These newer papers will often be more specific.

Explore! There's rarely a single answer to a research question. Click "Related articles" or "Cited by" to see closely related work, or search for author's name and see what else they have written.

Searching Google Scholar

Use the "author:" operator, e.g., author:"d knuth" or author:"donald e knuth".

Put the paper's title in quotations: "A History of the China Sea".

You'll often get better results if you search only recent articles, but still sort them by relevance, not by date. E.g., click "Since 2018" in the left sidebar of the search results page.

To see the absolutely newest articles first, click "Sort by date" in the sidebar. If you use this feature a lot, you may also find it useful to setup email alerts to have new results automatically sent to you.

Note: On smaller screens that don't show the sidebar, these options are available in the dropdown menu labelled "Year" right below the search button.

Select the "Case law" option on the homepage or in the side drawer on the search results page.

It finds documents similar to the given search result.

It's in the side drawer. The advanced search window lets you search in the author, title, and publication fields, as well as limit your search results by date.

Select the "Case law" option and do a keyword search over all jurisdictions. Then, click the "Select courts" link in the left sidebar on the search results page.

Tip: To quickly search a frequently used selection of courts, bookmark a search results page with the desired selection.

Access to articles

For each Scholar search result, we try to find a version of the article that you can read. These access links are labelled [PDF] or [HTML] and appear to the right of the search result. For example:

A paper that you need to read

Access links cover a wide variety of ways in which articles may be available to you - articles that your library subscribes to, open access articles, free-to-read articles from publishers, preprints, articles in repositories, etc.

When you are on a campus network, access links automatically include your library subscriptions and direct you to subscribed versions of articles. On-campus access links cover subscriptions from primary publishers as well as aggregators.

Off-campus access

Off-campus access links let you take your library subscriptions with you when you are at home or traveling. You can read subscribed articles when you are off-campus just as easily as when you are on-campus. Off-campus access links work by recording your subscriptions when you visit Scholar while on-campus, and looking up the recorded subscriptions later when you are off-campus.

We use the recorded subscriptions to provide you with the same subscribed access links as you see on campus. We also indicate your subscription access to participating publishers so that they can allow you to read the full-text of these articles without logging in or using a proxy. The recorded subscription information expires after 30 days and is automatically deleted.

In addition to Google Scholar search results, off-campus access links can also appear on articles from publishers participating in the off-campus subscription access program. Look for links labeled [PDF] or [HTML] on the right hand side of article pages.

Anne Author , John Doe , Jane Smith , Someone Else

In this fascinating paper, we investigate various topics that would be of interest to you. We also describe new methods relevant to your project, and attempt to address several questions which you would also like to know the answer to. Lastly, we analyze …

You can disable off-campus access links on the Scholar settings page . Disabling off-campus access links will turn off recording of your library subscriptions. It will also turn off indicating subscription access to participating publishers. Once off-campus access links are disabled, you may need to identify and configure an alternate mechanism (e.g., an institutional proxy or VPN) to access your library subscriptions while off-campus.

Email Alerts

Do a search for the topic of interest, e.g., "M Theory"; click the envelope icon in the sidebar of the search results page; enter your email address, and click "Create alert". We'll then periodically email you newly published papers that match your search criteria.

No, you can enter any email address of your choice. If the email address isn't a Google account or doesn't match your Google account, then we'll email you a verification link, which you'll need to click to start receiving alerts.

This works best if you create a public profile , which is free and quick to do. Once you get to the homepage with your photo, click "Follow" next to your name, select "New citations to my articles", and click "Done". We will then email you when we find new articles that cite yours.

Search for the title of your paper, e.g., "Anti de Sitter space and holography"; click on the "Cited by" link at the bottom of the search result; and then click on the envelope icon in the left sidebar of the search results page.

First, do a search for your colleague's name, and see if they have a Scholar profile. If they do, click on it, click the "Follow" button next to their name, select "New articles by this author", and click "Done".

If they don't have a profile, do a search by author, e.g., [author:s-hawking], and click on the mighty envelope in the left sidebar of the search results page. If you find that several different people share the same name, you may need to add co-author names or topical keywords to limit results to the author you wish to follow.

We send the alerts right after we add new papers to Google Scholar. This usually happens several times a week, except that our search robots meticulously observe holidays.

There's a link to cancel the alert at the bottom of every notification email.

If you created alerts using a Google account, you can manage them all here . If you're not using a Google account, you'll need to unsubscribe from the individual alerts and subscribe to the new ones.

Google Scholar library

Google Scholar library is your personal collection of articles. You can save articles right off the search page, organize them by adding labels, and use the power of Scholar search to quickly find just the one you want - at any time and from anywhere. You decide what goes into your library, and we’ll keep the links up to date.

You get all the goodies that come with Scholar search results - links to PDF and to your university's subscriptions, formatted citations, citing articles, and more!

Library help

Find the article you want to add in Google Scholar and click the “Save” button under the search result.

Click “My library” at the top of the page or in the side drawer to view all articles in your library. To search the full text of these articles, enter your query as usual in the search box.

Find the article you want to remove, and then click the “Delete” button under it.

• To add a label to an article, find the article in your library, click the “Label” button under it, select the label you want to apply, and click “Done”.
• To view all the articles with a specific label, click the label name in the left sidebar of your library page.
• To remove a label from an article, click the “Label” button under it, deselect the label you want to remove, and click “Done”.
• To add, edit, or delete labels, click “Manage labels” in the left column of your library page.

Only you can see the articles in your library. If you create a Scholar profile and make it public, then the articles in your public profile (and only those articles) will be visible to everyone.

Your profile contains all the articles you have written yourself. It’s a way to present your work to others, as well as to keep track of citations to it. Your library is a way to organize the articles that you’d like to read or cite, not necessarily the ones you’ve written.

Citation Export

Click the "Cite" button under the search result and then select your bibliography manager at the bottom of the popup. We currently support BibTeX, EndNote, RefMan, and RefWorks.

Err, no, please respect our robots.txt when you access Google Scholar using automated software. As the wearers of crawler's shoes and webmaster's hat, we cannot recommend adherence to web standards highly enough.

Sorry, we're unable to provide bulk access. You'll need to make an arrangement directly with the source of the data you're interested in. Keep in mind that a lot of the records in Google Scholar come from commercial subscription services.

Sorry, we can only show up to 1,000 results for any particular search query. Try a different query to get more results.

Content Coverage

Google Scholar includes journal and conference papers, theses and dissertations, academic books, pre-prints, abstracts, technical reports and other scholarly literature from all broad areas of research. You'll find works from a wide variety of academic publishers, professional societies and university repositories, as well as scholarly articles available anywhere across the web. Google Scholar also includes court opinions and patents.

We index research articles and abstracts from most major academic publishers and repositories worldwide, including both free and subscription sources. To check current coverage of a specific source in Google Scholar, search for a sample of their article titles in quotes.

While we try to be comprehensive, it isn't possible to guarantee uninterrupted coverage of any particular source. We index articles from sources all over the web and link to these websites in our search results. If one of these websites becomes unavailable to our search robots or to a large number of web users, we have to remove it from Google Scholar until it becomes available again.

Our meticulous search robots generally try to index every paper from every website they visit, including most major sources and also many lesser known ones.

That said, Google Scholar is primarily a search of academic papers. Shorter articles, such as book reviews, news sections, editorials, announcements and letters, may or may not be included. Untitled documents and documents without authors are usually not included. Website URLs that aren't available to our search robots or to the majority of web users are, obviously, not included either. Nor do we include websites that require you to sign up for an account, install a browser plugin, watch four colorful ads, and turn around three times and say coo-coo before you can read the listing of titles scanned at 10 DPI... You get the idea, we cover academic papers from sensible websites.

That's usually because we index many of these papers from other websites, such as the websites of their primary publishers. The "site:" operator currently only searches the primary version of each paper.

It could also be that the papers are located on examplejournals.gov, not on example.gov. Please make sure you're searching for the "right" website.

That said, the best way to check coverage of a specific source is to search for a sample of their papers using the title of the paper.

Ahem, we index papers, not journals. You should also ask about our coverage of universities, research groups, proteins, seminal breakthroughs, and other dimensions that are of interest to users. All such questions are best answered by searching for a statistical sample of papers that has the property of interest - journal, author, protein, etc. Many coverage comparisons are available if you search for [allintitle:"google scholar"], but some of them are more statistically valid than others.

Currently, Google Scholar allows you to search and read published opinions of US state appellate and supreme court cases since 1950, US federal district, appellate, tax and bankruptcy courts since 1923 and US Supreme Court cases since 1791. In addition, it includes citations for cases cited by indexed opinions or journal articles which allows you to find influential cases (usually older or international) which are not yet online or publicly available.

Legal opinions in Google Scholar are provided for informational purposes only and should not be relied on as a substitute for legal advice from a licensed lawyer. Google does not warrant that the information is complete or accurate.

We normally add new papers several times a week. However, updates to existing records take 6-9 months to a year or longer, because in order to update our records, we need to first recrawl them from the source website. For many larger websites, the speed at which we can update their records is limited by the crawl rate that they allow.

Inclusion and Corrections

We apologize, and we assure you the error was unintentional. Automated extraction of information from articles in diverse fields can be tricky, so an error sometimes sneaks through.

Please write to the owner of the website where the erroneous search result is coming from, and encourage them to provide correct bibliographic data to us, as described in the technical guidelines . Once the data is corrected on their website, it usually takes 6-9 months to a year or longer for it to be updated in Google Scholar. We appreciate your help and your patience.

If you can't find your papers when you search for them by title and by author, please refer your publisher to our technical guidelines .

You can also deposit your papers into your institutional repository or put their PDF versions on your personal website, but please follow your publisher's requirements when you do so. See our technical guidelines for more details on the inclusion process.

We normally add new papers several times a week; however, it might take us some time to crawl larger websites, and corrections to already included papers can take 6-9 months to a year or longer.

Google Scholar generally reflects the state of the web as it is currently visible to our search robots and to the majority of users. When you're searching for relevant papers to read, you wouldn't want it any other way!

If your citation counts have gone down, chances are that either your paper or papers that cite it have either disappeared from the web entirely, or have become unavailable to our search robots, or, perhaps, have been reformatted in a way that made it difficult for our automated software to identify their bibliographic data and references. If you wish to correct this, you'll need to identify the specific documents with indexing problems and ask your publisher to fix them. Please refer to the technical guidelines .

Please do let us know . Please include the URL for the opinion, the corrected information and a source where we can verify the correction.

We're only able to make corrections to court opinions that are hosted on our own website. For corrections to academic papers, books, dissertations and other third-party material, click on the search result in question and contact the owner of the website where the document came from. For corrections to books from Google Book Search, click on the book's title and locate the link to provide feedback at the bottom of the book's page.

General Questions

These are articles which other scholarly articles have referred to, but which we haven't found online. To exclude them from your search results, uncheck the "include citations" box on the left sidebar.

First, click on links labeled [PDF] or [HTML] to the right of the search result's title. Also, check out the "All versions" link at the bottom of the search result.

Second, if you're affiliated with a university, using a computer on campus will often let you access your library's online subscriptions. Look for links labeled with your library's name to the right of the search result's title. Also, see if there's a link to the full text on the publisher's page with the abstract.

Keep in mind that final published versions are often only available to subscribers, and that some articles are not available online at all. Good luck!

Technically, your web browser remembers your settings in a "cookie" on your computer's disk, and sends this cookie to our website along with every search. Check that your browser isn't configured to discard our cookies. Also, check if disabling various proxies or overly helpful privacy settings does the trick. Either way, your settings are stored on your computer, not on our servers, so a long hard look at your browser's preferences or internet options should help cure the machine's forgetfulness.

Not even close. That phrase is our acknowledgement that much of scholarly research involves building on what others have already discovered. It's taken from Sir Isaac Newton's famous quote, "If I have seen further, it is by standing on the shoulders of giants."

Academic Search Engines

by Bastis Consultores | Jul 12, 2020 | Thesis Development | 1 comment

You can’t ignore the fact that when someone thinks of searching online for task and project references, the first name that comes to mind is Google. However, when it comes to academic research, Google’s search engine doesn’t serve the purpose as it does in most cases. Their search results are not perfect sometimes. In this regard, in addition to Google, there are several search engines that are specially designed for academic research purposes. They can help you obtain important information without having to go through irrelevant or low-quality pages.

Starting with the search

Conducting an internet search may be second nature to you right now. But a little forethought about where you start doing your research can make your life a lot easier. Save time reading basic Google search results and use some of these tools to ensure results are up to academic standards. Below is a list of some of the best academic search engines that will help you get the research material you want quickly and easily, without compromising on quality.

Online Academic Text Search Engines

Academic info.

Academic Info contains a directory of the most useful links and resources within a specific subject area. You can browse this website for a list of useful research websites. This site also offers online degrees, online courses, and distance learning information from a selection of accredited online schools.

iSeek Education

iSeek is easily one of the best and most widely used search engines for academic research on the Internet. It has been specially designed with students, teachers and academics in mind. This search engine displays only reliable and relevant results that ultimately save you time and allow you to get your job done quickly. You can find safe, authoritative, smart and time-saving resources with iSeek.

Virtual LRC

Virtual LRC or The Virtual Learning Resources Center allows you to explore educational sites with high-quality information. It has indexed thousands of academic information websites. In addition to that, with personalized Google search, you will be able to obtain more refined results, which will help you complete your research in less time. It has been organized by professionals from around the world to provide students with excellent resources for academic assignments and projects.

Refseek is an academic search engine that is simpler than Google even in appearance. This search engine, however, does not claim to offer more results than Google. Instead, it removes results that are unrelated to science, academia, and research. The best thing about Refseek is that you can search for information related to a topic without being distracted by sponsored links. With a database of over a billion documents, web pages, books, magazines, newspapers, encyclopedias, and articles online, Refseek is one of the most recommended search engines for academic research.

Google Scholar

As its name implies, Google Scholar is Google’s academic search engine. Specially designed to search academic literature, it will help you find relevant information from the world of academic research. With Google Scholar, you can explore many sources, such as books, dissertations, articles, and abstracts from various academic publishers, professional societies, universities, and other websites.

Microsoft Academic Search

Microsoft Academic Search is Microsoft’s academic search engine. It gives you the ability to browse over 38 million posts. One of the best features of this search engine is that it provides trends, charts, and maps for your academic research. It contains more than 40 million publications and 20 million authors.

Google Books

Google Books allows web users to browse an index of thousands of books, from popular to old titles, to find pages that include their search terms. Once you find the book you’re looking for, you can review the pages, find reviews online, and learn where you can get a print copy.

WorldWideScience

WorldWideScience, which refers to itself as “The Global Science Gateway,” is operated by the Office of Scientific and Technical Information, a branch of the Office of Science within the US Department of Energy. The site uses databases from data from more than 70 countries. When users write a query, it reaches databases around the world. It shows results in English and translated from related magazines and academic resources.

Science.gov

Science.gov is operated and maintained by the Office of Science and Technical Information, the same department that collaborates with WorldWideScience.org. This search engine extracts more than 60 databases, more than 2,200 websites and 200 million pages of magazines, documents and scientific data. Search results can be filtered by author, date, subject and format (text or multimedia).

Wolfram Alpha

Wolfram Alpha describes itself as a computational knowledge engine. It does not provide both search results and search responses. Just type in a topic or question that might interest you, and the answer will appear without scrolling through the results pages. This is especially useful for those who need mathematical help.

Physical Activity and Academic Performance

Educational Resource Information Center

The Educational Resources Information Center (ERIC) is a tool for academic research with more than 1.3 million bibliographic records of articles and materials online. ERIC provides access to an extensive body of literature including journal articles, books, research summaries, conference papers, technical reports, policy papers, and more. With over eight million searches every month, it is no wonder why this search engine is one of the most recommended search engines.

Virtual Learning Resource Center

The Virtual Learning Resource Center (VLRC) is an online index that houses thousands of academic websites, all of which are selected by teachers and librarians from around the world. The site provides students and teachers with current and valid information for academic school and university projects using a compiled index of research portals, universities and Internet library guides recommended by teachers and librarians.

ResearchGate

ResearchGate is a unique social networking site for scientists and researchers. More than 11 million researchers present their work on the site, which totals more than 100 million publications, for anyone to access. You can search by publication, data and author, or even ask researchers questions. Although not a search engine that comes from outside sources, ResearchGate’s own collection of publications offers a great selection for any curious scholar.

Bielefeld’s Academic Search Engine (BASE) prides itself on being one of the world’s largest search engines, especially for academic resources on the web. Using 4,000 sources, the site contains results from more than 100 million documents. The advanced search option allows users to limit their research, so if you are looking for a book, review, lecture, video or thesis, BASE can provide the specific format you need.

Infotopia describes itself as an alternative secure Google search engine. The academic search engine retrieves results that have been selected by librarians, teachers, and other educational workers. A unique search function allows users to select a category, ranging from art to health, science and technology, and then view a list of internal and external resources related to the topic. So if you can’t find what you’re looking for on the Infotopia pages, you probably

PubMed Central

This site is perfect for those who study any career related to health or science. PubMed Central is operated by the National Center for Biotechnology Information, a division of the US National Library of Medicine, the database contains more than 3 million full-text journal articles. It is similar to PubMed Health, which is specifically for health related research and studies, and includes citations and abstracts from more than 26 million articles.

If you are investigating legal issues, Lexis Web should be your reference for any query related to the law you may have. The results are drawn from legal sites, which can be filtered by criteria such as news, blog, government, and commercial. Users can also filter results by jurisdiction, practice area, source, and file format.

Conclusions

If you want your work to be of high quality, then you certainly need to gather information from genuine and reliable sources. The sources mentioned above can be of great help so that your research has the appropriate information. Ultimately, they will allow you to have quality project and task references. As you will see, the information available is very extensive and you can feel overwhelmed in most cases. At Online-Tesis.com, we are here to help you in any aspect you need: either in the search for information or with the development of the thesis. We are here to fulfill your dream.

Summon and ProQuest

Summon has a relatively small number of dissertations, which you will find while running a general search. It is possible to filter your search by choosing CONTENT TYPE - Dissertation . To filter, you may need to use the More... option to see all content types, and then, once you  have selected the Dissertation option, select Apply : 

ProQuest Dissertations & Theses Global: Humanities and Social Sciences Large collection of doctoral and masters' dissertations.    Sotheby's Institute of Art - New York  dissertations from 2011 onwards are included. pass.  All content should appear reliably in Summon.   Some content from EThOS (see immediately below) is now duplicated in ProQuest, but not all: so it is better to search in Summon or directly in EThOS for UK doctoral dissertations.

EThOS Content should appear reliably in Summon. This is a database of doctoral theses (PhD and others) from the UK. Many are available in full online. Most are free to download, though a few institutions charge. It is mainly recent titles which are online, though some older dissertations which are much in demand have also been digitised .   You can request the digitisation  of dissertations which so far only exist in hard copy, via EThOS . However there is a charge for this, and  some waiting time.  

More options

There are many more options, listed here roughly in order of importance:

Global ETD (Electronic Thesis and Dissertation) Search Search engine for free online copies of dissertations. 

EBSCO Open Dissertations Largely duplicates content found in Summon, but includes some titles not found there.

Repositories Have been created by many universities and other degree-awarding institutions. These are free online stores of the scholarly material they have produced, usually including dissertations.  The key information about this kind of database is in the  repositories guide . The guide includes links to search engines for searching across many repositories at once.

DART-Europe E-theses Portal Provides free online copies of dissertations from many European countries, including some not found by Global ETD (see above).

Courtauld Institute: recently completed PhD theses .  A list of recent work from the Courtauld, more up-to-date than any other source. The PhDs are not available online; to read them you will need to contact the  Courtauld book library . Dissertations are stored off-campus, so you will need to make an appointment a few days in advance.

College Art Association: list of dissertations completed and in progress Details of PhD dissertations in art history and visual studies from US and Canadian institutions. Titles can be browsed by subject category or year. The dissertations themselves are not available via this site.

Theses Canada Doctoral and master's dissertations from Canada.  Many of the records in this database are only citations. Choose the option  Electronic theses  to limit your search to those available online.

Dissertation search engine

According to the actions for quality improvement provided by the Galician university system financing plan 206-2020, the University of Vigo has created this specific space in the institutional web site to offer our community members and society public information on undergraduate and masters dissertations defended in our institution.

Hereinto we present you a tool that will allow you to search by center, by year of defense or by word and discover the following data of each work: title, date of defense, director, tribunal members, faculty or school, content abstract and key words.   

Search engine

Regulations

An undergraduate dissertation is a personal assessment that each student performs autonomously under the centre mentoring and which should show the acquisition of the skills and contents associated with the degree. It cannot be in any case a previously presented assessment in any subject of the degree, even though it might integrate or develop working lines started during any stage of the degree.

Hereunder we provide you with the University of Vigos's specific regulatory information which works as regulation for undergraduate and masters dissertations. Their goal is to unify the procedures that facilitate their development and their administrative management; try to keep their integration in the structure of teaching, based on the particular characteristics the project has within the subjects of the degree; and guarantee the students that the elaboration, defense and evaluation of their dissertation can properly develop:

• Regulamento para a realización do traballo de fin de grao
• Regulamento para a realización do traballo de fin de mestrado

Advice and training

The Linguistic Normalization Area provides the students with a guide to improve the linguistic quality in written Galician on undergraduate and masters dissertations. This guide is made up of different sections: linguistic observations; solutions to recurrent errors; keys to improve your dissertation; linguistic criteria adopted by the Universidade de Vigo; computer resources and tools; didactic material elaborated by the Area of Linguistic Normalization and annexes that solve, through lists of terms, questions related to abbreviations, diacritical accent, foreign words, acronyms, the periodic table of elements and abstract and generic and collective terms referred inclusive language:

Pay-eye for the AI —

Google might make users pay for ai features in search results, plan would represent a first for what has been a completely ad-funded search engine..

Kyle Orland - Apr 3, 2024 10:44 pm UTC

Google might start charging for access to search results that use generative artificial intelligence tools. That's according to a new Financial Times report citing "three people with knowledge of [Google's] plans."

Charging for any part of the search engine at the core of its business would be a first for Google, which has funded its search product solely with ads since 2000 . But it's far from the first time Google would charge for AI enhancements in general; the "AI Premium" tier of a Google One subscription costs $10 more per month than a standard "Premium" plan, for instance, while "Gemini Business" adds $20 a month to a standard Google Workspace subscription.

While those paid products offer access to Google's high-end "Gemini Advanced" AI model, Google also offers free access to its less performant, plain "Gemini" model without any kind of paid subscription.

When ads aren’t enough?

Further reading.

"SGE never feels like a useful addition to Google Search," Ars' Ron Amadeo wrote last month. "Google Search is a tool, and just as a screwdriver is not a hammer, I don't want a chatbot in a search engine."

Regardless, the current tech industry mania surrounding anything and everything related to generative AI may make Google feel it has to integrate the technology into some sort of "premium" search product sooner rather than later. For now, FT reports that Google hasn't made a final decision on whether to implement the paid AI search plan, even as Google engineers work on the backend technology necessary to launch such a service.

Google also faces AI-related difficulties on the other side of the search divide. Last month, the company announced it was redoubling its efforts to limit the appearance of "spammy, low-quality content"—much of it generated by AI chatbots—in its search results.

In February, Google shut down the image-generation features of its Gemini AI model after the service was found inserting historically inaccurate examples of racial diversity into some of its prompt responses.

Video captures boeing 737 engine cover breaking away during takeoff, boeing 737 flight video shows engine cover ripping away ... emergency landing.

A Boeing 737 had to quickly brake when the plane's engine looked like it was starting to fall apart ... and the whole ordeal was caught on video.

The Southwest Airlines flight, heading from Denver to Houston, took off Sunday morning ... when some of the passengers noticed a piece of metal ripped off the side of the plane and flapped around as the plane began its takeoff.

Scary moments for passengers on a Southwest flight from Denver to Houston when the engine cover ripped off during flight , forcing the plane to return to Denver Sunday morning. pic.twitter.com/BBpCBXpTsl — Sam Sweeney (@SweeneyABC) April 7, 2024 @SweeneyABC

Check out the video ... the engine cowling covering the sides of the giant turbine flies up, seemingly only held together by a few strands of stray metal -- at first, not slowing down the jet one bit.

However, once the piece breaks away and flies off, the pilots slowly rolled the plane to a halt with the turbine almost completely exposed.

Southwest Airlines Flight 3695 pic.twitter.com/M5fsyAQ2fZ — Bvrtender (@bvrtender) April 7, 2024 @bvrtender

Southwest tells TMZ ... the passengers onboard got off the plane safely and boarded another aircraft -- landing in Houston about three hours after their original estimated arrival time. The airline says it's looking into the mechanical failure.

This is just the latest in a series of mechanical headaches Boeing's facing ... remember, just last month a United Airlines Boeing 777 lost a tire right as it took off, smashing several cars below.

And, of course, the door of a different plane blew out during one flight, forcing the 737 Max 9 to make an emergency landing in Portland ... so, this latest issue seems more of the recent same for the plane-producing giant.

All's well that ends well, we guess ... though some people might be rethinking upcoming travel.

Engine Cover Dramatically Rips Off Southwest Airlines Plane During Takeoff in Denver

The engine cowling "fell off" and "struck the wing flap" of the plane during the incident on April 7, according to the Federal Aviation Administration

A Southwest Airlines flight was forced to make an emergency landing after the engine cover fell off during takeoff in Denver.

In a statement , the Federal Aviation Administration said it has launched an investigation after the aircraft’s crew reported that "the engine cowling fell off during takeoff and struck the wing flap.”

“Southwest Airlines Flight 3695 returned safely to Denver International Airport around 8:15 a.m. local time on Sunday, April 7,” the statement read in part.

The aircraft, a Boeing 737-800 plane that has been en route to William P. Hobby Airport in Houston, was towed to the gate, per the statement.

A spokesperson for Southwest Airlines told PEOPLE in a statement that the flight "landed safely after experiencing a mechanical issue."

The statement also noted that the plane was being inspected by maintenance teams, and that customers were rebooked on another flight that arrived in Houston three hours behind schedule.

"We place our highest priority on ultimate safety for our customers and employees," the statement continued, adding that an investigation into the incident is ongoing.

A passenger named Lisa C. told ABC News that the engine cover “peeled off within the first 10 minutes" of the flight.

"We all felt kind of a bump, a jolt, and I looked out the window because I love window seats, and there it was," she said.

Meanwhile, passenger Cooper Glass called the incident “frightening.” 

"People in the exit row across from me started yelling up to the flight attendants and showed them the damage," he told the outlet, adding that the pilot “did a great job on landing.”

The airline said no injuries were reported, according to CNN .

Per CNN, in recorded air traffic control audio, one of the pilots said that “several passengers and flight attendants heard something loud hit the wing.”

Engine cover of Southwest Airlines plane comes off during takeoff

The Federal Aviation Administration on Sunday said it will launch an investigation after the engine cowling of a Southwest Airlines plane fell off during takeoff in Denver and struck the wing flap. The cowling is the protective cover over the plane's engine.

Southwest Airlines Flight 3695 returned safely to Denver International Airport around 8:15 a.m. local time on Sunday after the pilot reported the incident, the FAA said. The plane was headed to William P. Hobby Airport in Houston.

In a statement, Southwest Airlines said it is working to get customers on their way to Houston on another aircraft after Flight 3695 landed safely in Denver and that its maintenance teams are reviewing the aircraft.

Frank Sanger, who was on the flight, expressed shock after getting a glimpse of the plane’s state when he deplaned.

“You could see the jet engine had a panel stripped away, all the way around,” Sanger said in an interview that aired Monday on NBC’s “TODAY” show.

This is the second incident in recent days involving a reported malfunctioning of equipment on a Southwest Airlines flight. The FAA is investigating a reported engine fire before takeoff at Lubbock Preston Smith International Airport on Thursday.

United Airlines flights have also recently faced safety issues, with eight incidents having been reported in the last two weeks.

Sasha Johnson, the vice president of corporate safety at United, said in a statement that the FAA will be playing a larger role in the company.
