I haven't posted book reviews much here before, but I think that might change. I just finished "Between the Stacks", by Barry Bowes (Landesman, 1979) and quite enjoyed it. Set in a public library in the UK, it follows the trials and tribulations of the staff at the Pike Lane library, told from the viewpoint of the (interestingly unnamed, throughout the book) senior assistant. It's quite amusing, while also illustrating the frustrations of the reference interview, being the unpaid babysitters, and many other well-known PL issues. The issues at Pike Place frame an introspective journey by the main character, who's trying to evaluate his future, both personally and professionally.
It's not an easy book to come by; there wasn't a copy anywhere in my state (thanks, ILL!). Amazon has a few used ones from international sources, and I'm pondering placing an order, but we'll see. Even Library Thing, with its gazillions of books, only shows four copies. If you do have access to it, though, give it a read!
