Google Scholar

When I have to do my works and I need references, information about the topic, investigations, etc. I go to Google Scholar, it is not the only one, I use Scielo too, but Google Scholar is my favorite, because you just put the keywords on the seeker and that's all!, many information, like papers and investigations appear instantly. The information can be ordered by date and you can choose a time interval if you need a particular time for your references. I usually use this site, everytime I have to work on an investigation project... I think every week I open this site. It is very useful. By other hand, Scielo, that it is a page like scholar, not always have correct information, you can't trust at all in the investigation details that gives you Scielo, instead in Scholar you get reliable resources.
I really recommended! It is helpful, fast, and efficient. If you can use it for your works, this is the link https://scholar.google.es/
See you !
