Many librarians have joined the social networking universe by creating accounts for themselves and their libraries on Facebook, Twitter, MySpace.Linkedln, etc. But what happens when your town administrator connects with you on a site you mostly use for interacting with old high school friends? What is the protocol when a school librarian friends their students? How do you deal with a user who posts inappropriate photos on a library’s page? This presentation explores best practices for mixing your personal and professional lives on social networking sites, considers policies that can set guidelines for staff and patron/student use of these sites and discusses other ways to keep a comment we made on Facebook or MySpace off the front page of the local newspaper.
