This document discusses how libraries can use blogs to disseminate information. It notes that blogs allow librarians to broadcast useful information to users and promote awareness of programs and services. Blogs enable two-way communication with patrons and can feature announcements, new materials, recommendations, notices and more. Maintaining a library blog requires considering the purpose, software, policies, and marketing the blog to users. Done well, a blog is an interactive and easy way for libraries to provide information to patrons.
