This document contains statistics and input-output measures for Colorado school libraries and media centers. High schools, middle/junior high schools, and elementary schools are each subdivided into sections by population. Each section includes the school identification (district, address, city, county, zip code); respondent identification (name, title, phone, fax, e-mail); service hours per typical week; library media staffing per typical week; activities of paid staff per typical week; computers with access to school library resources; Internet access for students; library media collection; library media usage per typical week; and annual operating expenditures. Totals for school library media centers are provided at the end of the report. Benchmarks for school library media centers in Colorado--ratios that should make it easier to compare an individual library media center's figures with those for other library media centers--are also provided and address both library media center resources and services.
