I've mentioned the blogs of the Pullen Library at Georgia State before, but I wanted to share two more subject-specific blogs that the library's subject specialists are producing:

Issues in Scholarly Communication - "A library weblog covering the Issues of Scholarly Communication for the faculty and students at Georgia State University." (RSS feed)

Social Sciences News - "A weblog featuring library related news, events, and resources for the Social Sciences at Georgia State University." (RSS feed)
