19 academic search engines every researcher should know

22 mayo, 2021

Although it is clear that huge amounts of information of all kinds can be found on the Internet, the truth is that, on certain occasions, the sources and their credibility are questionable. A fact that we cannot afford, especially if we are part of a research team, we have to present an important academic work and a long etcetera that you can already imagine.

However, fortunately, we find a series of specialized search engines; engines that will make things easier for you and that will guarantee the veracity of your data; an essential for anyone who wants to achieve a rigorous result, which will delight the scientific community. We are left with the following selection.

HighBeam Research


HighBeam Research has a specialized database for professionals and students from various sectors; a system in which you integrate articles, book citations, published research, specialized magazines and academic, texts and others. In fact, among its sources we even find the Washington Post, The Independent and even the Mirror.

A library Through which we can explore using various search parameters, including the name of the author, the subject in question, events, and so on. Likewise, its page is intuitive and is structured in several tabs. The search box is at the top, but we recommend that you enter a specific section for better results



Aimed at students, teachers and researchers in general, iSEEK focuses on the resources of universities, non-commercial organizations –NGO and others-, official websites, administrative and governmental entities, and so on. The result? An accurate and quality search engine that makes available to us and identifies the most interesting resources, ranging from specific material to activities and publications in this regard.

Of course, its interface leaves something to be desired, as it is typical of this class of tools: simple web, search box with a design that already borders on retro and searches limited (initially) to this “place”. In any case, this does not diminish your utility; at the end of the day, the important thing about the case.



Sponsored by the Institute of Educational Sciences of the Department of Education of USA (IES for its acronym in English), ERIC (Education Resources Information Center) is a virtual library specialized in academic matters. A huge database that the government of this country created in 1964 and that houses a varied bibliography: articles, magazines, works and the like.

In addition, it integrates a thesaurus, as well as a function that will allow us to access an advanced search, which is located to the right of the search box and which offers us a list of tips, shortcuts and tricks to make the most of the utility’s possibilities.

In this community, users and researchers will have the possibility to publish their research and essays and follow other members of the community who have common interests and so on. It is interesting, because you never know with whom we will share our resources, or with whom we will end up working. In addition, it has a tool that allows us to find out the activity of each profile, and that includes data from the number of visits, followers, comments and others, very useful information when determining the prestige of the person in question.

Biology Browser


As its name suggests, Biology Browser is focused on researchers in the field of Biology and its corresponding branches. It is very useful to find specific data that other search engines are unable to give us. In addition, its website is structured by categories and even integrates a calendar with activities, as well as five upper tabs that will allow you to carry out more searches concrete. It is from Reuters and has a sector news section.



One of the main virtues of RefSeek is its simplicity; a feature that students and users will appreciate. Its results include resources from verified web pages, books, encyclopedias, newspapers, specialized magazines, studies and published documents. For more advanced searches we recommend using the Boolean operators.

Science research


Free and public, Science Research uses the so-called federated search technology of the Deep Web to give us the most accurate results possible. In fact, it uses other specialized search engines and is able to avoid duplicities, select the most useful information, collate it and much more. Of course, it is still in beta, something that does not make it less useful or interesting. It comes with advanced search preferences and includes a guided self-tour to help you get the most out of it.



With more than 3,000 specialized magazines in the arts and humanities, JURN is a search engine that indexes titles of academic articles, doctoral theses of disciplines and artistic, ecological, economic, biomedical sciences, linguistics and humanities in general. It is structured by different categories and the last upgrade of its resources dates from March 12 of this year.



Perfect for students who are studying for a doctorate and must choose their thesis, as Teseo will tell them what are the topics that they have already investigated thoroughly. Obviously, their results can be used for all kinds of scientific work that requires minimal rigor.

The search engine (from the Ministry of Education, Culture and Sport) also generates interactive maps based on the terms it has found in different databases such as Scielo, Lareferencia, Redalyc, Csic, and Openair, among others. It can give problems with our connection (at least it is what has happened to a server).



Responding to the acronym of Network of Scientific Journals of Latin America and the Caribbean, Spain and Portugal, it is a scientific newspaper library that anyone has the option of accessing. It includes specific tools that provide us with the possibility of analyzing the production, dissemination and consumption of scientific literature. It has recently added a section designed for researchers and authors, a section in which it is possible to create a profile and identify certain works.



The best thing about Chemedia is that its resources (documents, articles, texts from specialized magazines and a wide range that also include the previous ones) can be downloaded in PDF format. Of course, its design leaves a lot to be desired and is not as exhaustive as the previous ones. It also does not contain advanced search parameters, a matter that complicates the matter for us.



One of the most popular, Dialnet also focuses on journals, theses, congresses of scientific researchers and others. It includes links to authors and collects all their work and even some quotes. It is also very useful in the journalistic field, as a documentary source. Although its design is somewhat variegated, its utility and performance manage to mitigate this inconvenience. In addition, it is in Spanish, something that will delight those less well versed in the Anglo-Saxon language.


Pdf Sb

Similar to Chemedia, PDF SB is a website from which you can read and download e-books for free in this format. The best of the case is that it has very specific content, among which we find research papers on various topics, as well as in different languages; something that opens up the community even more. On its cover you will find some recommendations, although we recommend using the search box. According to his statements, he has a database of up to 71,600 books, a not inconsiderable number.

CERN Document Server


Surely if you have ever seen the television series The Big Bang Theory, you are familiar with the European Council for Nuclear Research (CERN), a research body in Physics on which the Document Server depends. A digital archive that provides us with the reports, articles and the rest of the multimedia content that we find in this database in the purest Sheldo Cooper style. Just out of curiosity, their website is worth a visit.

Now, you must be very precise in your search terms; something that the body itself facilitates by putting at our disposal a complete guide of advice in this regard. In any case and as in almost all search engines, you can opt for Boolean operators. It has categories, sections, disciplines and even comes with recommendations and conferences.

World wide science


World Wide Science also integrates content from around the world and displays the results selectively, that is, in order of importance. Its purpose is to accelerate “scientific discovery and progress by searching for content around the world.” The platform is available in several languages ​​to favor this accessibility and has a somewhat more visual design. It also includes a section for news, contact and more.

The Scientific Electronic Library Online was created to give visibility to the scientific literature of the Caribbean and Latin America, mainly. Currently it has all the support of foundations and groups from all over the planet related to the community that is the protagonist of our article. “A model for cooperative electronic publication of magazines on the Internet”. Its website is also available in Spanish.


Science Gov

Another website in Spanish, it is the version in our language of the United States government website. An engine that indexes up to 60 databases and 200 million sites specialized in scientific information. It includes, like most of the previous ones, the advanced search option and even an image search section. The latter is very welcome and is missed in most tools of this class.

Microsoft Academic Search

Microsoft, on the other hand, and a few years ago, did not want to be left behind and launched an experimental project that it called (yes, it is not original) Microsoft Research. A place that not only indexes thousands of publications but is also capable of showing how certain elements are related; a very useful feature when it comes to finding similar material from authors who follow similar theories, studies on a specific topic limited to one year and a field of study, and so on.

Google Scholar


Google Academic can also be useful, since it integrates theses, summaries, books and others (just like the previous ones). Likewise, it allows us to find out related citations, as well as the bibliographic references of certain texts, track authors and related ones, and more. The breadth of disciplines results …
