The American Psychological Association is reconsidering its previously announced $2,500-per-article PubMed Central deposit fee. (See the updated Open Access News "APA Will Charge Authors for Green OA" posting.")
Here's an excerpt from the APA's just revised "Document Deposit Policy and Procedures for APA Journals":
A new document deposit policy of the American Psychological Association (APA) requiring a publication fee to deposit manuscripts in PubMed Central based on research funded by the National Institutes of Health (NIH) is currently being re-examined and will not be implemented at this time. . . . APA will soon be releasing more detailed information about the complex issues involved in the implementation of the new NIH Public Access Policy.
