Although Google is like an immense ocean where everything can be searched and found, if you are always in the specific search for information for your studies, you may be interested in knowing certain academic searchers that include content from your specialization. If you still do not know them, here we present some of them. Do you know these academic search engines?
Academic google
Also know as Google Scholar, is full of good information, especially referring to doctoral theses, summaries of different subjects, notes and good articles in all the areas of knowledge that have been and have been. For me this search engine was totally unknown until now and I have assumed that for many of you as well, so here I present it to you and four more lines up in this article I have left you the link in case you want to take a look at it.
ERIC search engine
Although it could well be, it is not a proper person's name. It is the acronym for Education Resources Information Center, or what is the same translated into Spanish, Institute of Education Sciences. It is a database, formed by the government of the United States in 1964, to accommodate documents, articles, specialized bibliography and other resources from various magazines and sites.
Here you have the link to the specific site (you have to handle English well).
Science Research
It is a free, public search engine that uses advanced "federated search technology" within the Deep Web. Its mission is to offer quality results by sending the query in real time to other recognized search engines and then collate, classify and eliminate duplicates of said search.
Here you can see their website.
Science
As well indicated in their own home page, Ciencia.Science.gov searches in more than 60 databases and on more than 2200 websites of 15 federal agencies, offering 200 million pages of authoritative scientific information from the US, including research and development results. The Ciencia.Science.gov website is governed by the Alliance Participants interagency.
CERN DocumentServer
Perhaps this site from the television series 'The Big Bang Theory' sounds familiar to you. The CERN is European Council for Nuclear Research, where he is currently concentrating mainly on knowing the interior of atoms. On this site, you can find a wide variety of articles, reports and multimedia content, totally free, which also have a very comprehensive guide of recommendations on search terms.
That said, we hope that these 5 great academic search engines can help you improve presentations and acquire new and more extensive knowledge.
