Over 200 brief reports and some 85 case studies, developed from responses to a national questionnaire, report the state of the art for new media activities in public libraries. Through these case studies of large and small libraries throughout the United States, a picture of public library use of television, audio programs, mediamobiles, plus all types of film is presented. Some of the library activity descriptions are rather general; others are quite specific. All reveal an interest in expanding media use; many indicate the clientele toward which the new media service has been directed; some also present cost and evaluation efforts. Survey responses are organized by state. The case study material is organized in media-specific groupings. A list of 25 sources of additional information is appended. (KB)
