if you don’t know about unpaywall and are researching something or studing or just want to have access to knowledge but don’t go to uni or whatever, it might be pretty helpful. it’s a free, legal browser extension widget thing that unlocks open access academia. it can unlock something like 17 million articles so it’s pretty useful if you want to keep up with academia but don’t have access to institutional repositories or subscription databases.
(sci-hub has more access afaik but yknow. illegally. and unpaywall is still pretty great, especially at pushing subscription databases to make more stuff open access by being a legit example of what pirate repositories have been pushing for so long)
