OUP reports on Oxford Open results (so far)

A press release today from Oxford University Press reports on the first year (since July 2005) of the OUP hybrid journal program, Oxford Open. Some highlights:

• Almost 400 OA papers have been published, in 36 of the 49 journals that are participating in Oxford Open.
• 10% of the authors publishing in OUP life sciences journals have taken the OA route, with 5% of the medicine and life sciences authors and 3% of the humanities and social sciences authors doing so.
• The journal with the highest number of OA papers is Bioinformatics, which published over 50 OA papers.

As someone who pays a lot of attention to serial prices, I thought it was interesting to note that the 2007 online subscription costs for three journals, Bioinformatics, Carcinogenesis and Human Molecular Genetics, will be adjusted to reflect the number of freely available articles these publications contained in 2005-2006. This is good to see (presumably, the prices will be adjusted downward) but I wonder what the threshold is for setting a cost adjustment into motion? How many OA papers does it take to do this?

OUP is going to carry on with the Oxford Open program. The 49 journals that are presently involved will continue and it is expected that other Oxford titles will join.
