This is a handbook designed for use by the Maryland library community to exert influence on behalf of libraries. Indicating the necessity to get federal support to libraries, it gives handy information about organizing for action. A chart of the Maryland legislative coalition and information network with the names and addresses of members is presented. It also lists members of the Maryland congressional delegation (senators and representatives) and tells how to effectively receive their support for library programs and legislation. Writing letters, telegrams, telephone calls, interviews and visits, and home district lobbying are techniques suggested. The handbook also provides brief background information on federal and state programs in Maryland libraries and refers to other sources for more detailed information. (CH)
