The information reported in this document characterizes libraries in California through statistical tables, profiling each library within the appropriate library type (public, academic, special, state agency, and county law). The data were gathered though the annual report forms for fiscal year 1985-1986 that were returned by 967 libraries of an estimated total of 1,200 California libraries (not counting school libraries). Presented in the statistical tables are data on activities (interlibrary loans borrowed and lent, circulation, total volumes, etc.), income, expenditures, staffing, and collections. These data are organized by library type and area population. Also provided is a state summary of library statistics for the current year, plus two preceding years, and figures from 1977-78--the watershed year before Proposition 13--which include total operating expenditures and salaries; library materials; full-time staff equivalents; total volumes; circulation; interlibrary loan borrowing and lending; and total number of reference questions answered during the year. A list of the libraries represented concludes this report. (CGD)
