Hi Kevin. Thanks for linking to the OATP tag library for “oa.dei”.
FYI, here’s the OATP tag library for the conjunction “oa.dei AND oa.publishers”:

OATP supports deep links like this to any boolean combination of tags. If you write me directly (peter.suber@gmail.com) I’d be happy to say more about how it works.
