As part of a series on library services to disadvantaged adults, this pamphlet provides guidelines for the use of community advisory committees in libraries: the duties and capabilities of such committees, their influence on the library, and their relationships with library boards. The size and composition of the committee are considered, as are four alternatives for the selection of members: election by the community, or appointment by the librarian, by organizations, or by public officials. In the final section, steps are outlined for writing policy, training members, and beginning the work of the advisory committee. A brief reading list is appended. (SL)
