Vols. for 1964-67 include annual statistics of Michigan public libraries for fiscal year preceding year of publication.

This is the fourth in a series of reports evaluating the Public Library Statistics (PLS) program, an annual census of public libraries in the United States. The census includes, in addition to a full count of public libraries and their outlets, a variety of statistics about the services provided by and, the financial condition and the staffing levels of public libraries. This report contains the results of an evaluation of the definitions and internal consistency of the staffing variables and a comparison of the statistics collected for these variables to selected statistics from independent sources. This evaluation was conducted to raise specific issues for discussion among members of the Federal State Cooperative System for Public Library Data. Chapter 1 evaluates the definitions used for the staff variables, while Chapter 2 considers the internal consistency of staff measures. Chapter 3 compares statistics from the public library census to those from other reference sources for public library staffing information. Four appendixes list the variables, libraries without paid staff, and library reports and directories, and present comparisons of dataset and other figures. (Contains 70 references and 14 tables.)
