The goal of this study was an appraisal of indexing coverage for the interdisciplinary field of toxicology. Information of research significance was limited to primary literature, defined as published documents containing original data from experimental work or case studies. (6 references) (Author/NH)

To compare computerized services in chemistry, pharmacology, toxicology, and clinical medicine of pharmaceutical interest, equivalent profiles were run on magnetic tape files of CA-Condensates," CBAC," Excerpta Medica," MEDLARS" and Ringdoc." The results are tabulated for overlap of services, relative speed of citing references, and unique…

Implications of research findings comparing structural characteristics of two data bases for the development of screening systems for substructure search are set out. (4 references) (Author/SJ)

An analysis of five commercial service centers and various data bases is presented. A current awareness profile covering both chemical and botanical fields was sent to each service center. The responses were evaluated on the basis of promptness, interaction with the user, and physical format of the listing, among other things. (Author/NH)

The data base coverage of these two services was examined and selected computerized searches performed. The results of this study provided some meaningful conclusions as to the general utility of these services. (3 references) (Author/NH)

The performance of CA Condensates" (CC) and Chemical Titles" (CT) based on analysis of precision and relative recall CT/CC" for 46 search profiles was studied for one year. The results are discussed in terms of the value of the systems as seen from the users' and the documentalist's point of view. (13 references) (Author/NH)

Methods for retrieval of information on chemical compounds utilizing several computer data bases are compared to determine scope of data base coverage. Preparation of search questions is outlined and comparative results are reported indicating the yield from each data base. (6 references) (Author/NH)

The relative retrieval performances of the CA Integrated Subject File (CAISF), CA Condensates, and a Merged File created from these two data bases were measured. Retrieval performance is reported in terms of recall, precision values, and costs. (Author/JB)
