Blogs are being used by libraries, and have been for a while. They provide immediate communication with their patrons, and generate interest from all segments of the community towards participation in their libraries. The give librarians ideas of what their local communities need and enjoy, and even what kinds of services to provide. They create an online sense of community, different from a true social physical interaction which library programs often provide (e.g. music events, cultural festivals, etc.). Most importantly, blogs not only let patrons express themselves, they are fun! A balance of a great, useful collection, online interactivity and resources, and live programs and enticing physical surroundings all help make libraries powerful community entities.
