Google is the master of world search, but something is missing. And that something is the reliability of the information it retrieves. Google indexes countless websites without taking into account the veracity of the content, it also shows search results based on your interests (advertising) and based on its algorithm for sorting the results (a mystery).
In fact, when looking for material for a job or a study on a certain area, you have to be very careful and separate what is important and relevant from what the search engine does not filter.
But all is not lost, fortunately there are libraries that can really give you the information you need without any financial or other non-informative purpose.
There are also a multitude of academic, school, science databases, science portals, electronic publications, free to access search engines that allow you to locate the information you need reliably and securely with a simple search.
The best academic and university search engines
SciELO – Scientific Electronic Library Online is a model for cooperative electronic publication of scientific journals on the Internet. Developed specifically to meet the needs of scientific communication in developing countries and in particular in Latin America and the Caribbean, the model provides an efficient solution to guarantee visibility and universal access to its scientific literature, helping to overcome the phenomenon known as lost science. .
WorldWideScience.org is a gateway to global science made up of national and international science databases and portals. WorldWideScience.org is scientific discovery and progress by providing a one-stop shop for databases around the world. It is multilingual and provides real-time search and translation of scientific literature spread globally.
Google Scholar offers an easy way to search for academic literature. You can search in many disciplines and sources: articles, theses, books, abstracts and opinions from academic publishers, professional societies, online archives, universities and other websites. Google Scholar helps you find relevant jobs in the world of academic research. (While I’ve mentioned a number of academic search engines for alternatives to Google in this post, Google Scholar should be considered.)
