An improved scientific information system is proposed involving dissemination of abstracts to indivduals by core abstract services followed by publication and distribution of individual articles. (Author/JB)

Progress in the development of advanced chemical information systems in the United Kingdom is briefly described. (8 references) (Author)

The journal coverage provided by Chemical Titles,'' Current Contents,'' Science Citation Index,'' Chemischer Informationsdienst,'' and Index Chemicus'' is discussed and compared with the CASSI list of the thousand primary journals most frequently cited by Chemical Abstracts.'' (10 references) (Author/NH)

An important function of an industrial information center is to control, not multiply, the reading problem by selective use of available commercial services. When necessary, and economically feasible, specialized internal services are developed. Some of these services are described. (6 references) (Author)

The development of scientific journals in Japan pertinent to chemistry is reviewed, and the current status of abstracting activities in Japan is described. (Author)

Scientists and engineers have solved their wordage and most other information problems through the creation and use of information analysis centers (IAC). IAC's synthesize, analyze, and compress pertinent information so that knowledge transfer remains effective. (Author/NH)

Terse conclusions which are concerned with the meaning of a document rather than the subject scope, have replaced abstracts at Hooker Research Center for progress reports. These terse conclusions are circulated to the entire staff and are also intended to aid in management decisions. (9 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…

The methodology of a technological forecast, integrating consultant, industrial, and academic input from three successive Delphi rounds, is presented. (11 references) (Author)

Analysis of the distribution of relevant answers to 41 search profiles among the 80 subject sections of Chemical Abstracts" revealed that the average profile requires 10 CA-subject sections for adequate coverage. The average printing expense could be reduced 25 percent by searching the individual profiles in the appropriate subject sections. (5…

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)
