Auto-extract obvious links to papers from articles #18
Description
We should automatically pick up papers from articles which are already well-linked to academic papers.
How to identify them?
A lot of urls have DOI numbers in them, and we could probably just pick up any link to a journal website (although maybe exclude links to just the front page, say).
Should probably also mark these sources in some way, so we can give credit - eg a leaderboard of publications who's articles are well sourced.
