Recent regulations require anyone publishing research funded by the NIH to post it to their digital archive no later than 12 months after publication. They have guidelines requiring the author to insist on copyright changes with publishers. Journals pretty much have to go along because all the big boys have NIH money.
All in all, I think the NIH is probably justified in going this way. Subscriptions are so high that too many little players can’t maintain a library. The current publishing house of cards looks to be collapsing.
Good info to know. Thank you for your reply.
