Alexander Calhoun is small but it does the job. If you're looking for a library with a large selection of books and lots to browse through, this may not be the place for you. It never seems overly busy, though, and the people who work here are nice enough to not make faces when I make my quarterly trip into the library to pay fines. Since I usually reserve & pick up books, it works well for me overall.
I'm about equidistant between this library and the one in Signal Hill but drive past this one on a much more frequent basis.
A yearly membership is only $12 (if you're not constantly paying fines, like me) and the library has a pretty good online account management system & library catalogue, of course. If only they'd put fine payments online :)
