NASA Aerospace Database Subject Scope ... An Overview

National Aeronautics and Space Administration Scientific and Technical Information Program Washington, DC 1993 This publication was prepared by the NASA Center for AeroSpace Information, 800 Elkridge Landing Road, Linthicum Heights, MD 21090-2934, (301) 621-0390. NASA Aerospace Database Subject Scope ... An Overview

The NASA Scientific and Technical Information (STI) Program manages the vast amount of information pertinent to aerospace research and development and makes this information available to NASA and the aerospace community worldwide. The main tool in carrying out this mission is the NASA Aerospace Database, a publicly available subset of the NASA STI Database. The NASA Aerospace Database contains over 2,000,000 citations to reports, journal articles, and other publications.

This booklet outlines the subject scope of the NASA Aerospace Database. It lists the topics of interest to NASA and places them within the framework of broad aerospace subject catagories. For detailed explanations of the subjects themselves, see the NASA Scientific and Technical Information System ... Its Scope and Coverage, December 1988 (NASA SP-7065).

13.ABSTRACT (maximum200 words)

Outlined here is the subject scope of the NASA Aerospace Database, a publicly available subset of the NASA Scientific and Technical (STI) Database. Topics of interest to NASA are outlined and placed within the framework of the following broad aerospace subject categories: aeronautics, astronautics, chemistry and materials, engineering, geosciences, life sciences, mathematical and computer sciences, physics, social sciences, space sciences, and general. A brief discussion of the subject scope is given for each broad area, followed by a similar explanation of each of the narrower subject fields that follow. The subject category code is listed for each entry.
