More on the impact advantage of OA

Michael J. Kurtz and five coauthors, The Effect of Use and Access on Citation, a preprint, January 2005. (Thanks to Stevan Harnad.)
Abstract: It has been shown (S. Lawrence, 2001, Nature, 411, 521) that journal articles which have been posted without charge on the internet are more heavily cited than those which have not been. Using data from the NASA Astrophysics Data System (ads.harvard.edu) and from the ArXiv e-print archive at Cornell University (arXiv.org) we examine the causes of this effect.
