My Topic: Twitter and Libraries

I am going to be gathering and annotating resources about libraries' use of Twitter. I am particularly interested in public libraries, though I may also include some resources about academic, school, or special libraries. I'm interested in learning how libraries' use of Twitter may differ from their use of other social networking and Web 2.0 tools; how libraries' use of Twitter has changed and developed in the few years since this social networking tool was created; whether libraries primarily use Twitter as an attempt to reach out to teens and younger adults, and whether this is successful; what problems or complications may arise from libraries' use of Twitter; and other related issues.
