The Proceedings of the National Academy of Sciences (PNAS) introduces an open access option for authors. The option, which is to be evaluated after an experimental period, allows authors to pay a $1,000 surcharge to make their articles available for free via PNAS Online and PubMed Central immediately upon publication. In a survey informing the decision, nearly half of the respondents were in favor of an open access option. According to Nicholas R. Cozzarelli, PNAS Editor-in-Chief and Professor of Biochemistry and Molecular Biology at UC Berkeley, “PNAS is starting by experimenting with an open access option for authors. It is a compromise between open access for all articles and doing business as usual.” See the press release.
