| Description | 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 number of postings (documents) indexed by each subject term from 1968 to data. 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). Over 595,000 book postings for NALNET Books held by NASA Libraries are included under the NLN column. CSTAR postings as well as some previously unreported series are listed under the 'other' column. The distribution of 18,748,083 postings among the 17,304 Thesaurus terms is tabulated on the last page of Combined File Postings Statistics. |
