CJACS file

A literature database well suited for obtaining the information we seek is the Current Journals of the American Chemical Society (CJACS) file. Like the CA file, CJACS is produced by the CAS and is searchable through the STN International network. The CJACS database has the advantages of being large (145,001 papers) and interdisciplinary, as well as covering some of the journals with the highest impact - on chemistry. The records in the database include not only abstracts, but also the full text of the articles and all the references and...

Figure 3 Computational chemistry papers (Figure 2) in the CJACS file as a percentage of the total number of articles in CJACS the percentage has increased each year. Note that 1989 s percentage does not show a large jump like in 1988 and 1990. This is because the use of Gaussian was flat in 1989 with respect to 1988, while mentions of MOPAC and QCPE actually dipped in 1989, as seen later (Figures 12, 13, and 22).

Figure 7 Yearly number of publications in the CJACS file mentioning three other molecular modeling programs. CDL is Chemical Design Ltd. The search queries for the curves were (1) macromodel, (2) pcmodel or serena, (3) chemx or chem(w)x or chemical(w)design(w)ltd or chemical(w)design(w)limited, (4) serena, and (5) chemi-cal(w)design(w)ltd or chemical(w)design(w)limited.

Figure 9 Yearly number of publications in the CJACS file related to MM2, MM3, or MMX. The search queries for each curve were (1) mm2 and (force(w)field or molecular(w)mechanics), (2) (mm2 or mm3) and allinger, (3) mm3 and (force(w)field or molecular(w)mechanics), (4) (mmx or mm(w)x) and (force(w)field or molecular(w)mechanics), and (5) (mm2 or mm3) and (technical(w)utilization or tripos or molecular(w)design).

Figure 10 Number of publications per year in the CJACS file mentioning CHARMM, AMBER, GROMOS, ECEPP, or OPLS. The academic version of CHARMM has the last M in uppercase, whereas the spelling CHARMm is used by MSI. Database searching is not case sensitive hence the developer s name was used as part of some of the queries. The search queries for each curve were (1) charmm and (simulation or modeling) and karplus, (2) amber and (simulation or modeling) and kollman (3) biomos or gromos, (4) ecepp, and (5) opls.

Figure 12 Number of publications per year in the CJACS file mentioning semiem-pirical MO programs MOPAC, AMPAC, AMSOL, or ZINDO. The search queries for each curve were (1) mopac, (2) ampac, (3) amsol, and (4) zindo.

Figure 15 Number of publications per year in the CJACS file mentioning LHASA. The search query was lhasa.

Figure 19 Yearly number of publications in the CJACS file mentioning CLOGP or Medchem. The search queries were (1) clogp and (2) medchem.

Figure 22 Number of publications per year in the CJACS file mentioning Quantum Chemistry Program Exchange and two programs it distributes, MM2 and MOPAC. The queries used to search the CJACS file were (1) qcpe or quantum(w)chemis-try(w)program(w)exchange, (2) (qcpe or quantum(w)chemistry(w)program(w)ex-change) and mopac, and (3) (qcpe or quantum(w)chemistry(w)program(w)exchange) and (mm2 and (force(w)field or molecular(w)mechanics)).

CJACS Plus Images, which is the CJACS file (Chemical Journals of the American Chemical Society), allows users to search and retrieve articles from 26 ACS journals. With full text dating back to 1982, complete page images including illustrations, halftones, graphs, and tables are now available for all articles from 1992 forward. 

The ACS primary journal system may be upgraded to handle automatically structures, line drawings, and scanned images. This would provide for both publication of the images and their eventual inclusion in the full-text CJACS file recently loaded on STN International. 

Search for publications about piceol is documented in full text format in the CJACS file (Chemical Journals of the American Chemical Society) (Fig. 124).
