INTRODUCTION

The NASA Combined File Postings Statistics is published semiannually (January and July).

This alphabetical listing of postable subject terms contained in the NASA Thesaurus is

used to display the numbers of postings (documents) indexed by each subject term from 1968

to date. The postings totals per term are separated by announcement or other media into

STAR, IAA, NLN, and OTHER columnar entries covering the NASA document collection (1968 to

date).

Nearly 594,000 book postings for NALNET Books held by NASA Libraries are now included

under the NLN column. CSTAR postings as well as some previously unreported series are now

listed under the "other" column.

File postings statistics for the Alternate Data Base covering the NASA collection from

1962 through 1967 were published on a one-time basis in September 1975. Subject terms for

the Alternate Data Base are derived from the Subject Authority List, reprinted 1985, which

is available upon request.

The distribution of 16,919,195 postings among the 17,105 Thesaurus terms is tabulated on

the last page of Combined File Postings Statistics.
