Public library advocacy is support given to a public library for its financial and philosophical goals or needs. Most often this takes the form of monetary or material donations or campaigning to the institutions which oversee the library. Originally, library advocacy was centered on the library itself, but current trends show libraries positioning themselves to demonstrate they provide "economic value to the community." History of public library advocacy Letter writing campaigns are chiefly intended to inform law makers, library officials, and citizens about the ramifications of decisions regarding public libraries and to promote library-related causes. Letter writing has been a valuable form of communication among public library advocates. A well-timed and hand-crafted email or strategically sent letter can be a potent mechanism used to sway the decisions of elected officials and the masses. Letters are practical because they can be distributed to many individuals and can serve as representation for public library advocates who cannot attend crucial meetings or rallies. Public libraries frequently use programming to increase awareness of the valuable services and resources that they offer to the community. Some of these programs offer information and educational resources for library advocates and librarians while others are directed towards increasing public knowledge of library services and resources. Library Card Sign-up Month is celebrated in September as a part of The Smartest Card campaign. During Library Card Sign-up Month, the library card is frequently promoted as the most important card that individuals can have in their wallets. Library Card Sign-Up Month is a popular program across the United States. The ALA logo for the Smartest Card campaign is, “The Smartest Card. Get it. Use it. @ your library”. "Turning the Page: Building Your Library Community" is an advocacy education and training program funded by the Bill and Melinda Gates Foundation.
