A structured approach to advocacy for K-12 school librarians focuses their energy on an active path that showcases library programs and resources and expresses the essential role librarians serve in school and student success.Keeping a library program vital requires regular reflection about current practices and a willingness to implement changes that will position the library and library staff should they be threatened with elimination. Simply Indispensable: An Action Guide for School Librarians helps librarians do just that. The book begins with an explanation of the need to act and then offers a systematic approach to taking action. Each chapter is devoted to an active path: attracting patrons; interacting with teachers, parents, administrators, and the community; communicating; reacting to "situations;" working for reinstatement if the worst happens, and more.The book covers advocacy-from the subtle exercise of developing excellent programs to the overt outreach of Legi-Days. Additionally, there is specific information about what to do when the RIF notice or pink slip arrives or if cuts are made, including how to properly close a library. After putting these actions into effect, school librarians will have a cadre of supporters ready to speak for them should the need arise.
