Books? Yeah, we've got them too...
Recently we've started to add novels, comics and art books related to video games to the collection. Like Warcraft and Halo novels, The Art of... books, and the like. These books will be in the regular AAEL books collection (i.e. not kept down in the archive room) so you can check them out and read them like any other book in the library.
The books also have their own New Books feed: http://www.lib.umich.edu/aael/feeds/aaelgamebooks.xml
