Intended for use by librarians and library administrators, this document presents information derived from the 1981 Annual Report/System Membership Applications submitted by public libraries in Texas. Statistics are included on library populations served; library holdings; library circulation; library services; interlibrary loan transactions; library expenditures; library funding; library personnel; professional salaries; and various output measures including total circulations per capita, turnover rates for bookstock and library holdings, total circulations per staff member, program attendance per capita, and reference questions answered per capita. The analysis is divided into four sections, three of which present the statistics organized on the basis of regional library systems, groups of population served, and total expenditures. The fourth section presents percentages for the distribution of library expenditures by such variables as region, source of income, size of population served, and type of expenditure. Brief instructions and illustrations showing how to read the tables are provided. Appendices comprise the survey form and instructions for its use as well as definitions of terms and variables used in the analysis. (ESR)
