Hi everyone! When I think in one website that I visited most often is:
https://scholar.google.cl/. Frequently I used Google to find everything that I need: concept, meaning of something, synonyms, etc. In my career I use Scholar Google so much because I'm working in my thesis project right now, so I found differents academic documents for the theorical framework of it. In Scholar google you can find a lot of academic text in differents language. I searched always in spanish, but now, sometimes I reed sometimes in english too. When you search in english you can obtain a much more bigger database for your investigation
In scholar google you can obtain documents in varied formats, sometimes people publics their documents in .pdf and I prefer this format. I have read books of many authors in .pdf and it is a better economy for me, and for the planet too, because I avoid print it. Sometimes people public in the website in html fomart, I dont like so much this because I can't save the document in my library, but even then I consider it is very utility for any research.
Good luck with your research and your thesis too!
