In contrast to the character string searches that were done on the full articles in the CJACS and CJWILEY databases, a different method of counting was used with MMCC Results. The newsletter usually indicates which of the... 

Figure 23 Total number of times three general purpose molecular modeling packages were mentioned in the CJACS and CJWILEY database files during the years 1987—1993. A logarithmic scale is used, to increase the visibility of the bars for the smaller data set.

One of the most thorough ways of retrieving data from the literature is through searching databases of full articles. We find, from a detailed analysis of CAS s CJACS database, year-by-year increases in mention of many computational chemistry programs. Because of the sheer size of CJACS (145,001 articles), we expect it to be quite representative of the chemical literature as a whole. In addition, we have shown corroborative data from CAS s CJWILEY database and from the MMCC Results newsletter. 

A second smaller source of data on software usage is another database file available from the Chemical Abstracts Service. The file CJWILEY covers the full text of polymer journals (Table 3) published by John Wiley Sons. CJWILEY lists 8775 articles published in the seven-year period 1987—1993. Unfortunately, CJWILEY does not include Wiley s Journal of Computational Chemistry. By comparing findings from CJWILEY to the CJACS results, however, one can ascertain whether there are different patterns for modeling polymers versus modeling molecules in general.
