I decided to follow a library on Twitter. The Casa Grande Library in ?? (see below for the hunt to find out where they are located) uses Twitter to announce events, new books, etc. They provide nice links to the catalog records for the material. But they blast out way too many tweets. Just this morning they updated 17 times. I'm going to remove them as it is making it difficult to follow my librarian friends.
The search for Casa Grande Library: Looking at their catalog I still can't figure out where they are located. Finally going to their web page and scrolling WAY down to the very bottom is a map with their mailing address. They are in Arizona.
