Hey Sylvain,
We met someone at ALA that recommended that we should talk to Google Scholar about a mechanism like that: they surface institutional collection copies from citation information, giving readers options for versions to access. That particular contact hasn't followed up with us: I just sent a reping email. If anyone has contacts in the Google Scholar org, I would love to find a way to work with them. Eventually we would like to create a centralized project-wide search mechanism that allows us to both search our existing partnership
We are also in the process of supporting WikiProject X (James Hare) in creating a framework for us to document citations, for surfacing suggested sources to editors based on topical area project (
https://phabricator.wikimedia.org/T111066 ). I think that tool has a lot of potential for surfacing OA collections to editors as well.
If you want to explore this, its well within our interest: not necessarily top priority at the moment, but something we can work into our asks for partners and support of volunteers.
Cheers,
Alex Stinson
