The National Information Standards Organization (NISO) recently published the 5th edition of the standard ANSI/NISO Z39.7, Information Services and Use: Metrics and Statistics for Libraries and Information Providers – Data Dictionary. The purpose of the Z39.7 Data Dictionary is to assist the information community in the identification, definition, collection, and interpretation of statistical data used to describe the current status and condition of libraries in the United States.
Originally published in 1968 with the title Library Statistics, the standard has evolved through its subsequent editions, culminating in an online data dictionary and new title in the 2004 edition. In 2008, NISO moved the standard from periodic to continuous maintenance and established the Z39.7 Standing Committee to maintain the standard.
The Z39.7 Data Dictionary is available in open access on the NISO website at http://z39-7.niso.org/. A downloadable PDF version of the standard is also available. Users of the standard are encouraged to submit suggestions to the Z39.7 Standing Committee at any time. Information on the continuous maintenance process is available from the Committees’ webpage at www.niso.org/workrooms/z39-7.
