Our own Yvonne Jones has just published her article "Oversized and underused: Size Matters in Academic Libraries" -- gotta love that title! -- in the July 2006 College & Research Libraries (you can find it here via Rollins.)
It is a useful study of how college libraries define and shelve oversized books, which are in my experience surprisingly vexing problems, and whether this impacts the overall level of use. She found that how the library handled these materials didn't make too much of a difference, probably because users are now often browsing and finding such books in the OPAC rather than by browsing the shelves.
College & Research Libraries is one of the top journals in academic librarianship, so congratulations to Yvonne.
