Suggestions are made for a variety of easy and low cost public relations ideas for use by libraries, especially school libraries and learning centers. Basic principles are outlined for the use of bulletin boards, mass media publicity, displays, library handbooks, telephone service, and ephemera such as bookmarks and newsletters. For school libraries, instructions are provided for book fairs, faculty inservice programs, and student orientation. Sources for art supplies are provided as an aid to display work. (SL)
