This document summarizes a project to integrate Web 2.0 technologies into the work of local public health departments. Library staff and university partners worked with two health departments, one large urban and one small rural. They identified ideas for using blogs, wikis, social media, and other tools. A survey found that while staff were personally familiar with some technologies, they had concerns about professional uses, like maintaining privacy and dedicating work time. Lessons learned included the need for policy guidance and showing how technologies could efficiently help essential public health work.
