A manual search of Journal Citation Reports provides information which would be particularly useful for librarians interested in forming special collections and difficult to obtain by other methods. (Author/MBR)

Reviews the problems involved in citation analysis and discusses the possible magnitude of error involved when these problems are overlooked or ignored. Problems identified include formal influences not cited, biased citing, informal influences not cited, self citing, different types of citations, variations in citation rate, and technical…

The structure and interrelations of the biomedical journal literature are investigated as a preparatory step for studies of biomedical research activity. (Author)

The hypothesis that the mechanistically identifiable citation link characteristic (i.e., mention of a given reference more than once within the same research paper) indicates a close and useful relationship between a citing and a given cited paper is tested and accepted. (Author)

Describes early Hebrew citation indexes, both embedded and book-length, and discusses terminological variation, format, precision of locators, the order of index entries and assumption of user knowledge, knowledge of the compilers, and recommendations for further research. (59 references) (LRW)

Describes a study that tested the status-role hypothesis by examining the citation networks of geographic journals at distinct time points. The need to consider time factors and disciplinary conditions when interpreting clustering representations is discussed. (25 references) (CLB)

Presents the results of a study of Science Citation Index (SCI) as a source for developing indicators of international scientific activity. Journal counts based on SCI and British Library Lending Division (BLLD) cataloging records are compared and reference patterns in key journals are described. Eleven references are listed. (JL)

Reports the results of a qualitative analysis of cocited author retrieval performance. The discussion covers the effects on recall of first author only access and the ability of cocited author search techniques to enhance retrieval performance. Multiple author frequency data is also presented. (14 references) (CLB)

Indicators of national scientific activity were derived from counts of 500,000 publications and millions of citations in large scientific journals in 7 major disciplines, six major countries, and a time span from 1965 to 1972. (Author/PF)

Illustrates a method to divide large citation database files into clusters of journals without requiring the use of arbitrary starting points. Results are discussed relative to biomedical literature. (Author/FM)

Suggests a new ranking scheme especially adapted for hypertext environments in order to produce more effective retrieval results and still use Boolean search strategies. Topics include Boolean ranking schemes; single-term indexing and term weighting; fuzzy set theory extension; and citation indexing. (64 references) (Author/LRW)

Gives a method for filtering out the important authors on and sources for information in crucial current areas of scientific research. (Author/PF)

Reports on the history of bibliometrics, citation indexing, and citation analysis in the legal field. Private and commercial ventures dating back to the nineteenth century, the influence of legal bibliometrics on bibliometrics in other fields, and possibilities for future development of legal citation analysis are discussed. (27 references) (LRW)

Two articles discuss the clustering of composite representations in the Cystic Fibrosis Document Collection from the National Library of Medicine's MEDLINE file. Clustering is evaluated as a function of the exhaustivity of composite representations based on Medical Subject Headings (MeSH) and citation indexes, and evaluation of retrieval…

Describes a study that explored the relationship between the number of cited references used in a citation search and retrieval effectiveness, analyzing the overlap among posting sets retrieved by various combinations of cited references. Findings showed that the more cited references used for a citation search result, the better the performance.…
