Wikipedia:OABOT - Wikipedia, the free encyclopedia

"Our community does not prohibit or even discourage citing paywalled sources, but at the same time there is absolutely no prohibition on surfacing OA versions right alongside those citations. Indeed, a good citation will have as much information as possible to let the reader find (and use) it in the way that is easiest for them.

Aim: Create a bot that can add links to citations to available free-to-read versions (alongside paywalled resources)."
