This comparison of the results of two surveys of library instruction programs in California academic libraries, conducted in 1974 and in 1980 by the California Clearinghouse on Library Instruction, includes discussions of the number of survey returns by library type; teaching methods used for library instruction; materials used to teach course-related instruction, formal credit courses, self-paced credit instruction, and non-credit instruction; libraries by type in 1980 reporting instructional activities such as self-guided tours and library handbooks; and use of audiovisual media by library type. These survey results are also compared with those of two national surveys reported by Project LOEX (Library Orientation/Instruction Exchange) in 1973 and in 1979. Eleven tables and four references are provided, as well as a copy of the 1980 questionnaire and a list of nine commercially published texts used in library instruction courses. (RBF)
