Abstract: Abstract : The DTNSRDC Library Subject Thesaurus, which exists both as a printed document and as an on-line computer file, supports the indexing and retrieval functions of the library's automated storage and retrieval system. The hierarchical structure of the vocabulary permits generic retrieval. For example, a search on naval vessels will retrieve documents that had been indexed under all naval ship types. Several 'switching' relationships provide an automatic cross-referencing capability.
