Kaufman-Wills presents “The Facts about Open Access”

I saw a story today in the Chonicle of Higher Ed about a presentation on Open Access at the London Book fair. An abstract of the presentation is on the LBF website, and the actual presentation is on the ALPSP web site (scroll to the bottom). It looks like some of the results are very interesting. In particular, it points out that not all Open Access journals use the “author pays” system, and it points out that many commercial journals DO use this system.
