IRs are for institutional research output. They are not for institutional buy-in. (That would be an institutional library.) The way OA works is that an institution makes its own research output free for all, to maximize its visibility, usage and impact. By symmetry, it also gets access to the output of all other IRs for its users, for free. No subscriptions, no fees, no need for an institutional affiliation for anyone but the author of the work in the IR. That’s OA. Almost-OA is when some of the IR material is still under a publisher embargo, so it is deposited Closed Access instead of Open Access and can be accessed using the IR’s almost-immediate “email eprint request” Button during the embargo. Almost OA is not OA, but together with universal Immediate Deposit mandates, it will soon usher in universal OA. In contrast, Joseph Esposito’s “Almost OA” is just institutional consortial licenses. It has no more to do with OA than being Almost Pregnant has to do with parity.
