Cormaggio posted this link on en.Wikiversity's Colloquium (equivalent of the village pump) about a comparison and review of Wikiversity:
While it isn't about Wikibooks directly, there is mention that some of the free textbooks being used by courses in Wikiversity do indeed come from Wikibooks. It's the strong collaboration between these two projects, the simultaneous production of free textbooks and free course materials, that offers the biggest promise to education available in open content. To that effect it is almost worth wondering whether Wikibooks and Wikiversity would have been better served as a combined project, instead of being separated into two. Of course there would be many kinks to work out (perhaps too many), especially considering the differing attitudes of these two projects with respect to fundamental issues such as NOR.
