From the Introduction: Why Do I Need a Policy?
Every library — academic, public, and school (public, private, charter, independent, and international) — should have a comprehensive written policy that guides the selection, deselection or weeding, and reconsideration of library resources. The most valuable selection policy is current; it is reviewed and revised on a regular basis; and it is familiar to all members of a library’s staff. The policy should be approved by the library’s governing board or other policy-making body and disseminated widely for understanding by all stakeholders.
