Although I respect Kristin's work and suspect that there is a small OA citation advantage, I am not convinced by these data. For one thing, I doubt that most of the results reach statistical significance. For the fields other than mathematics, there are so few OA papers with 1 or more citations that the margin of error is likely be greater than any apparent difference between OA and non-OA papers. Even the trends aren't clear; looking at the data for papers with one citation, there seems no difference for engineering, an OA advantage for philosophy, and a non-OA advantage for political science. I think we're trying to find significant differences in what is probably noise. I also don't understand how these data exclude Phil's hypothesis. Since Kristin seems to define quality in terms of citations, then the logic seems self-referential: how would one detect a difference in citation due to instrinsic quality when one has defined quality as number of citations?

Data I collected for philosophy, political science, engineering and mathematics do not support this hypothesis that OA causes more citations for better articles only (given that one uses overall citations as a rough measure of quality). These data were collected for my article, "Do Open Access Articles Have a Greater Research Impact?" (C&RL Sept 2004, http://eprints.rclis.org/archive/00002309/), but at that time I had not looked at the distribution of OA and non-OA articles by citations. Graphs of those results are posted at http://www.lib.ncsu.edu/staff/kantelman/OA_by_citations.xls. These data show OA citation advantage across all articles with more than zero citations. It could be argued that OA helps to get the first citation. It's also striking, I think, how similar the graphs are even though the rates of OA vary greatly between these disciplines (between 17% and 69%). ________________________________________ Kristin Antelman Associate Director for the Digital Library NCSU Libraries Box 7111 Raleigh, NC 27696-7111 (919) 515-7188 Fax (919) 515-3628
