This study examines the value of blogs as information dissemination tools. We based our finding on blogs created by libraries, librarians or information professionals. A relatively exhaustive list of blogs written in English was compiled from data obtained from several lists/directories. The blogs were extensively characterized considering several aspects. The findings indicate that blogs have a high professional potential and are a novel information channel for transferring information both to fellow professionals and to other users of the Web. The main challenge at this point of time is to increase the readership of these blogs.
