Subject Indexing -- DDC and the DoD Technical Libraries.

Abstract

The subject indexing produced by the Defense Documentation Center and a randomly selected number of DOD technical libraries is examined to determine: (1) Whether DDC or the DOD technical libraries assign more subject indexing terms per document; and (2) What percentage of subject indexing terms assigned by the DOD technical libraries are identical or similar to those used by DDC. The author makes the following conclusions: (1) DDC assigns more subject headings per document than almost all DOD libraries; (2) A little over 50% of the terms assigned by the DOD libraries are used by DDC analysts to catalog the same documents; (3) DDC and the DOD libraries are practically using the same vocabulary with which to index documents.
