The 1979 "Index of Institutions of Higher Education, by State and Congressional District" reports the names of the senators, representatives, and other elected officials of the 96th Congress, their states and congressional districts, and each institution of higher education located in the districts. Also included are the control, type, sex designation of the student body, fall 1977 enrollment, city name, zip code, telephone number, chief executive officer, and 1978-79 undergraduate tuition and required fees of each institution. Control distinguishes between public and private institutions, and private institutions are reported as independent, nonprofit, or profit, or other (affiliated with a religious group). The institutional types are university, four-year and two-year. The sex designation for the student body of each institution is shown as men, women, coeducational, or coordinate--separate colleges for men and women. The index is a companion volume to the "Education Directory, Colleges and Universities, 1978-79." The index reflects the biennial changes in the U.S. Congress and additional information on the institutions listed in the directory. (SW)
