ANSI/NISO Z39.4, Criteria for Indexes is now published!

The National Information Standards Organization (NISO) announces the publication of its updated ANSI/NISO Z39.4, Criteria for Indexes, incorporating feedback from the public comment period earlier this year. It replaces the original ANSI/NISO Z39.4 standard (Guidelines for Indexes and Related Information Retrieval Devices), last updated in 1984, and is an updated and expanded version of NISO’s Guidelines for Indexes and Related Information Retrieval Devices (a technical report, TR02-1997).

The updated standard provides guidelines for the content, organization, and presentation of indexes used for the retrieval of information. It deals with the principles of indexing—regardless of the type of material indexed, the indexing method used, the medium of the index, or the method of presentation for searching.
