incorrect reference?

Posted by Bill_Hooker on 18 Jun 2009 at 09:47 GMT

from the text: "...the $1,700 in page charges that the average PNAS author already pays (Cozzarelli et al. 2004)."

The Cozzarelli et al reference contains no figure for average page charges.

Thank you for your interest in this article. The reference to the Cozzarelli et al. article relates to the first part of the sentence, about the recent PNAS survey which found that "nearly 50% of PNAS authors expressed a willingness to pay an “open-access surcharge” of $500 or more to make their papers available for free online immediately upon publication". Information on PNAS' page charges is available on the journal's website: Current page charges for an average article (assuming 6 pages, 3-4 colour figures, and Supporting Information) would amount to $1570-1800.
