Conversion of the Chemical Abstract Service scientific literature data base from Standard Distribution Format to a center-oriented file format, STF, is described. A tape file format is described in which variable length logical records, possibly longer than the blocksize, may be stored safely. (7 references) (Author/NH)

Peer reviewedAnd Others; Eckermann, E. H. – Journal of Chemical Documentation, 1972
Almost three million records covering approximately 175,000 chemical compounds and involving multiple disciplines have been recorded in the Army Antimalarial Drug Program. Maximum compartmentalization of files together with a complete method of interfacing files and a unique number system has made it possible to manage this system. (2 references)…

Peer reviewedRowlett, Russell J.; Tate, Fred A. – Journal of Chemical Documentation, 1972
Among other improvements in chemical nomenclature used in the Chemical Registry System, Chemical Abstracts Service intends to standardize the fundamental principles for naming cyclic structures so that procedures for the derivation of ring names can become more amenable to computer generation and translation.

Peer reviewedAdamson, George W.; And Others – Journal of Chemical Documentation, 1973
A major problem in the design of screening systems for substructure searches of chemical structure files is the development of a methodology for selection of an optimal set of structural characteristics to act as screens. Distributions of several structural characteristics of the Chemical Abstracts Service Registry System are summarized. (13…

Peer reviewedFlanagan, Carolyn M. – Journal of Chemical Documentation, 1973
The findings of the first two parts of a five-part study are presented. The objectives of the first two parts were to determine the overlap of primary journal coverage among the services and to compare selection processes for the same articles by the different services. (4 references) (Author/SM)

Peer reviewedAnd Others; Zipperer, W. C. – Journal of Chemical Documentation, 1973
Minimum, maximum, and average lengths and frequency counts for the data elements in the Chemical Substance and General Subject segments of the Standard Distribution Format (SDF) files distributed by Chemical Abstracts Service are presented. (5 references) (Authors)
