I havent seen anyone talk about this yet so im making a post.
So lets say you’re researching something for a paper (or just for fun) and the research paper you want to read is behind a paywall, or the site makes you create an account first, or makes you pay to download, or limits you to only 5 free articles, or otherwise makes it difficult for you to read what you want.
do not fear! copy the link to the article
go to sci-hub.se (the url is always changing so its best to check out whereisscihub.now.sh to find what the current url is)
slap the article link in there
