Unpaywall is a handy little open source project, available to use as a browser extension, which makes it easier to find open access copies of journal papers.
I just thought I'd share this here for those who may need it. I find it very useful!
@irina No problem. Hope it's helpful!
@invaderxan It asked me for permission to access data for all my browsing activity before I could use it. 😒 
@rushkeating The plugin needs to see the page you're looking at to know when you're on a journal website and which article you're looking at. It needs to "change" the page to give you a link to the free copy.
If you're uncomfortable with that, you can simply query the database directly. It's more time consuming but it gives the same result.

@masklayer @invaderxan this is really cool and would be useful to put on the browsers in a public library

@invaderxan oh this is neat! I wonder if my sciencey academic friends know about it 🤔 gonna pass it along, thanks for sharing
@KnivesOnly Anytime! I first heard about it from tumblr. Social media can be really helpful for sharing these things!
@invaderxan totally agreed! It's one of my favourite things
@invaderxan I've been testing Kopernio, too. Both very useful for finding OA versions!
