What's in your library's catalog?

I've been thinking about OER and trying to discover it - including free ebooks and open textbooks... and at the same time I have been looking around for books that others are recommending in MobiMOOC on mobile learning. Of course Mohamed Ally's book Mobile Learning: Transforming the Delivery of Education and Training was recommended. The hard copy is available for sale, but it is also available as a free e-book. I checked a couple of libraries - hard copy listed, but not the free e-book. WorldCat has bibliographic records for print, Netlibrary, etc., but I didn't spot a bibliographic record for the free e-book. Should the OPAC list material that library doesn't own or license? Should libraries help us discover OER? If not, how will that job get done? (Google Books doesn't seem to note the free version.) I know - It's the old problem of staff time, whatever costs are necessary to upload and update records for what is supposed to be free material.
