NASA Scope and Subject Category Guide

摘要

This guide provides a simple but effective tool to assist aerospace information analysts and database builders in the high-level subject classification of technical materials. Each of the 76 subject categories comprising the classification scheme is presented with a description of category scope, a listing of subtopics, cross references, and an indication of particular areas of NASA interest. The guide also includes an index of over 2,380 specific research topics cross referenced to the subject categories. The CD-ROM version hyperlinks this index to the subject categories. In addition to subject classification, the guide can serve as an aid to searching databases that use the classification scheme, and is also an excellent selection guide for those involved in the acquisition of aerospace literature. The CD-ROM includes the guide in PDF for printing.
