That would be super helpful when I find a journal article that's on Pubmed, but doesn't have a DOI attached to it anywhere that I can find. Anyone wanna take on this project? I already use: Open Access Button: https://openaccessbutton.org/ https://openaccessbutton.org/ UnPaywall: https://unpaywall.org/ https://unpaywall.org/ And Sci-Hub when I have too, but sometimes I just can't find the DOI on some articles.
