PNAS Free Online Back to 1915
From Ken Fulton, Publisher, PNAS:
The Proceedings of the National Academy of Sciences (PNAS) announced that its legacy content dating back to volume 1, issue 1, in 1915 is now digitally archived, searchable, and freely available on the PNAS web site at http://www.pnas.org/.
PNAS presents its free digital archive in conjunction with its 90th anniversary. The digital collection spans nearly a century
of seminal scientific research, and comprises more than 390,000 pages and 80,000 articles.
PNAS is a break-even operation and relies about equally on author fees and on subscription fees to cover its operating costs. PNAS subscribers gain access to the most recent 6 months of published content. [Hardin Library has a subscription to PNAS: http://proxy.lib.uiowa.edu/login?url=http://www.pnas.org/]
