From a Library Developments Blog Post by Valicia Greenwood:
Direct your browser to the Texas Public Library Statistics page, https://www.tsl.texas.gov/ld/pubs/pls/index.html. We have compiled information from the Texas Public Libraries Annual Reports, from reporting years 1996 through 2017.
Summaries and totals for all the libraries in the state can be found in the Texas Public Library Statewide Statistics. The format has been revised and condensed this year.You can compare your library to up to four others using the Individual Library Statistics and Comparison Charts.
Using the Five-Year Trend Charts, trends for a variety of measures since 2012 can be viewed and used by selecting the library’s city and then simply downloading an Excel chart for the subject you wish to present.
