Check out the ALA's Advocacy University. Grouped by topic or by library type, this resource provides links to research, publications, kits, and more to help you make sure our libraries are recognized as the vital programs they are.
Find information on budgets and funding, dealing with challenges to materials, working with elected officials, internet safety and more! Resources specific to school library programs include teaching standards, press materials, data collection tools, and information on the ALA's Presidential Task Force on School Libraries.
Take note of the ALSC's campaign called "Kids! @your library" which includes some great (free!) promotional materials!
You can find permanent links to these and other great resources on the Advocacy Toolkit tab at the top!
