Corporate Source - DTIC maintains a Corporate Source Authority System (CSAS) which lists all organizations that have contributed information to the Technical Reports, Research Summaries, or Independent Research and Development databases. Each organization is assigned a 6-digit Source Code used to search these databases for information authored or sponsored by the organization. Each Corporate Author record displays the root (highest) element of the organization, the parent (next higher) element of the organization, any sub-organizations or former names, and the organization's Source Code. From the Corporate Source results page, users can insert Source Codes into Guided Search queries.
DTIC Thesaurus - The thesaurus provides a broad multidisciplinary subject term vocabulary that reduces the need to search multiple synonyms. Subject terms, called Descriptors, are organized into hierarchies, where narrower terms are linked to broader terms. After performing a Thesaurus search, a user can insert a Descriptor directly into the Guided Search queries for Technical Reports, Research Summaries, and Independent Research & Development databases.
Subject Category Guide - DTIC has identified 25 broad subject fields and 251 groups to categorize the areas of scientific and technical interest. These Fields and Groups provide the structure for subject grouping of documents in DTIC's Technical Reports, Research Summaries, and Independent Research & Development collections. Fields and groups numerical codes may be used to locate relevant results in those databases.
