Description
Summary:This report describes the need for and establishment of vocabulary controls for a coordinate indexing retrieval system involving multidisciplinary terminology. Included in the controls is an improved fragmentation system for the handling of organic compounds. The elimination of role indicators from the indexing procedures is also briefly discussed. The system that is described was established to handle the scientific and technical documents that are on file in the library facility of the Air Force Materials Laboratory. Approximately 16, 000 documents have been indexed and the revised thesaurus contains slightly over 10,000 terms. See also AD428423.
