The American Museum of Natural History is now providing OA to the full back runs of all four of its journal and book series:

American Museum Novitates (from 1921)
Anthropological Papers of the American Museum of Natural History (from 1907)
Bulletin of the American Museum of Natural History (from 1881)
Memoirs of the American Museum of Natural History (1893 - 1930)
(Thanks to antropologi.info.)

Comment. AMNH launched its institutional repository in January 2006 and has been very busy filling it up ever since.

Some museums are progressive in allowing free scholarly use of their images (e.g. Metropolitan Museum of Art, Victoria and Albert Museum), but I don't know of another museum with its own OA repository, let alone the AMNH's commitment to filling it. Kudos to all involved.
