INTRODUCTION

The NASA Thesaurus Supplement replaces the former 6-Month Cumulative Listing of theNASA Thesaurus Changes. This cumulative supplement to the NASA Thesaurus 1982 edition,incorporates all of the information normally contained in the previous publication as well as twonew features: complete hierarchies and access vocabulary. It is hoped that the additionalinformation and the improved legibility will make this a more useful product than itspredecessor. Subsequent issues of the supplement will be cumulative and will be issued everysix months. For detailed information on the use of the NASA Thesaurus Supplement, consultthe front matter of the NASA Thesaurus 1982 edition.

Users are encouraged to consult the online NASA Thesaurus for the most complete and up-to-date information. Addenda to old hierarchies in the 1982 edition of the NASA Thesaurus arenot given because they are readily found in the online NASA Thesaurus. Inclusion of such afeature would have substantially increased the size of the publication. In using the hierarchiesin the online NASA Thesaurus, users are cautioned that these hierarchies list broad andnarrow terms and not their interrelationships. The online NASA Thesaurus does not show theexact relationship when there are more than three broad and/or narrow terms.

New terms to this issue are indicated with a bullet and larger type. Designed for browsability,each new term appears in the format of the following example:

• Earthnet

Many times cross references are later made postable terms. These are shown in Part 3. Whennew cross references are added to older terms, the term that is referred to is not listed unlessit is also a new term. For older terms check the printed or the online NASA Thesaurus.

Many Comments or suggestions about this publication, including suggestions for new terms,should be directed to the Lexicographer, NASA Scientific and Technical Information Facility,P.O. Box 8757, BWI Airport, Maryland 21240.
