Based upon data collected annually by the American Association of Junior Colleges (AAJC), this directory provides information on 1,111 community, junior, and technical colleges and two-year branch campuses in the United States and its territories, including 1970 and 1971 data on enrollments and personnel. Following introductory material on the scope of the directory, projections are presented for total enrollments and numbers of colleges for 1972 to 1981. Next, the directory lists colleges alphabetically by state or country and provides the following information for each: location; chief administrative head; telephone number; year classes began; type of control or affiliation; AAJC membership; state recognition or accrediting agency; types of programs (i.e., transfer and/or occupational); co-educational or single-sex status of school; October 1970 enrollments broken down for full- and part-time freshman, sophomore, and unclassified students; total October 1970 enrollment; enrollment in summer session 1971; October 1971 enrollment; full- and part-time faculty and administrators in 1971-72; tuition or all-inclusive fee; and type of academic calendar. Next, tables provide statewide enrollment and personnel summaries for all institutions and for public and independent colleges and show the distribution of two-year colleges by size. Lists of changes in institutions since the previous year, community and junior college organizations, and state administrators for two-year college education conclude the directory. (AYC)
