Library networked statistics and performance measures are important indicators of the use, uses, and users of networked services that libraries offer their patrons.
This article focuses on three efforts to develop and standardize library network statistics and performance measures. In particular, the article discusses, compares, and contrasts selected aspects of the International Standards Organization (ISO), U.S. public library network statistics, and Association of Research Library (ARL) efforts. The three approaches attempt to capture, describe, and present library networked activities in similar ways through similar approaches – yet they differ in key areas. It is important to note that there are a number of national and international efforts underway that continue to research the library network statistics and performance measure environment.
