Intended to aid librarians, this guide explores the methods librarians can and do use to influence government publishers, printers, distributors, and indexers of government information, as well as those who create and interpret the policies governing those programs. Case studies from Canada, England, and the United States are cited to illustrate the effectiveness of librarian involvement with government information dissemination. Seventeen ways in which librarians can exert their influence are detailed as are several areas in which such influence is needed. References are included. (FM)
