Further exploration reveals that http://doai.io , http://doi2oa.erambler.co.uk/ and https://oadoi.org/ (now http://unpaywall.org/ ) don't resolve handles in the way that https://doi.org/ does.
Having said that, at least some are open source ( https://github.com/jezcope/doi2oa) so it shouldn't be too hard to add. cheers stuart -- ...let us be heard from red core to black sky On Fri, 17 Aug 2018 at 14:20, Stuart A.
