This digest discusses ways in which public libraries deal with latchkey children who spend their after-school hours at public libraries while their parents are at work. Research conducted in 1990 of 110 public libraries revealed that almost all libraries encountered unattended children after school hours, and that most libraries surveyed were not adversely affected by latchkey children. Nine successful or innovative programs in public libraries in the United States and Canada that address the needs of latchkey children are described. These programs often involve transportation of children from schools to the library; using retired senior volunteers; theater presentations; making available arts and crafts, games, computers and typewriters, read-along books, films, and refreshments; activities, including theater presentations, swimming, and field trips; and instruction in etiquette, survival and safety skills. Some programs offer activities designed to foster self-esteem and creativity, child care referral services for parents, and special services for children of immigrants. Recommendations for libraries include interacting with community agencies; conducting research; recruiting children as future library patrons; creating a separate area for children's use; using volunteers; and providing arts and crafts supplies. The digest is adapted from the book, "Latchkey Children in the Library and Community: Issues, Strategies, and Programs" (Oryx Press, 1991). Eight references are cited. (BC)
