I haven’t been a student for many years. When I was in school at first we used portals like
- Science Direct
Next, Google Scholar came out and seemed to be a superset of all of those, so it was the best when I left off.
I was on a phone call with a university class a couple of years ago and they told me there was some newer “meta portal” (my term) that was along the same lines but even better than Google Scholar. I can’t recall the name and it’s not obvious which one it is when I try to figure it out by searching the web.
