Evidence against an OA advantage for The Astrophysical Journal

Michael J. Kurtz and Edwin A. Henneken, Open Access does not increase citations for research articles from The Astrophysical Journal, a preprint deposited in arXiv September 6, 2007.

Abstract:   We demonstrate conclusively that there is no "Open Access Advantage" for papers from the Astrophysical Journal. The two to one citation advantage enjoyed by papers deposited in the arXiv e-print server is due entirely to the nature and timing of the deposited papers. This may have implications for other disciplines.
