Based upon data collected annually by the American Association of Community and Junior Colleges (AACJC), this directory provides information on 1,165 community, junior, and technical colleges, and two-year branch campuses of four-year institutions in the United States and its territories, including 1972 and 1973 data on enrollments and personnel. Following introductory material on the scope of the directory, abbreviations and key terms are explained. Next, the directory lists the colleges alphabetically by state or country and provides the following information for each: location; chief administrative head; telephone number; year college classes began; type of control or affiliation; AACJC membership; state recognition or accrediting agency; enrollments for October 1972 broken down by full- and part-time enrollment of freshman, sophomore, unclassified, and total students; total October 1972 enrollment; enrollments in summer session 1973; total enrollment in October 1973; full- and part-time faculty and administrators in 1973-74; tuition or all-inclusive fee; and type of academic calendar. Next, tables provide enrollment and personnel summaries by state for all institutions, and for public and independent colleges, and show the distribution of size of enrollments in two-year colleges. Changes in institutions since the previous year are examined next, followed by lists of community and junior college organizations and state administrators and an alphabetical listing of schools.
