This report includes data furnished by public library directors to the Wyoming State Library and gives a statistical picture of the condition of public libraries throughout the state for fiscal year 1998 (July 1997 through June 1998). Information is taken from a national survey of the Federal-State Cooperative System for Public Library Data. Libraries are listed in order of county population to allow for more relevant comparisons between library systems. The tables present the following data on county library systems: (1) a five-year (1994-98) comparison; (2) services, including number of employees, library visits, reference transactions, circulation, children's program attendance, library loans, and library borrows; (3) collections, including bound materials, audio materials, video materials, subscriptions, total collection, collection age, and expenses; (4) expenditures, including salaries, benefits, collection expenses, operating expenditures, capital outlay, format expense, and access expense; (5) revenues, including Mill Levy, and county, city, state, and federal revenue; (6) other income, including gifts/donations, interest, fines, fees, and grants; (7) staffing; and (8) other comparisons, including registered patrons to population, services per capita, collection size per capita, and collection turnover. Each table also lists population estimate, number of registered patrons, and number of locations. Two additional tables present data on service and collection by city/town. (AEF)
