Further to my previous post “NIH Mandate and PMCIDs” we’ve been looking into linking to articles on publishers’ sites from PubMed Central (PMC). There are a couple of ways this happens currently (see details below) but these are complicated and will lead to broken links and more difficulty for PMC and publishers in managing the links. Crossref is going to be putting together a briefing note for its members on this soon.
The main issue we are raising with PMC, and that we will encourage publishers to raise too, is why doesn’t PMC just automatically link DOIs? Most of the articles in PMC have DOIs so this would require very little effort from PMC and no effort from publishers and would give readers a perisistent link to the publisher’s version of an article.
