Items studied in a library survey of U.S. institutions of higher education included shifts in decision-making bodies, unionization, and tenure. From the 1032 questionnaires returned, these findings resulted: (1) 175 of 1025 have unionized library staff--135 of them since 1971; (2) 496 of 1018 librarians responding said they were organized as a faculty or in a similar structure; 22 of 37 academic research libraries answering this question on structure responded similarly; for all libraries claiming faculty or faculty-like structure, 30 percent said that this organization represented a change since 1971; (3) in many areas of the study, 4-year colleges offering no graduate degrees reported the least amount of change; in many categories, the largest institutions (with 10,000 or more full-time enrolled students) reported the highest degree of change. Findings are summarized in 18 tables and discussed; the questionnaire and coding sheets are included. (Author/JD)
