Recommended sources for the selection of school library materials are listed in this annotated bibliography intended to aid schools in developing their library collections. The sources cover a variety of media including fiction, nonfiction, biographies, picture books, reference books, filmstrips, films, video programs, microcomputer courseware, magazines, and records. Each entry includes the title, author, publication date, price, an annotation, and a symbol indicating the appropriate educational level (elementary or secondary schools). New or revised editions are also flagged with a symbol. Several microform catalogs and aids to facilitate ordering books are also included, and a listing of publishers' addresses is provided. (MES)
