Movements in research interests, particularly towards biological methods of control, correlations between these sectors, and the difficulties encountered in the construction of a…

A ranking list of biochemistry periodicals was prepared on the basis of citations in the Annual Review of Biochemistry'' for 1968-70. This list brings out the predominant position of biochemical research in the total scientific effort today, and the increasing bias of cognate disciplines towards biochemical methodologies.

Topics include assessments of the most influential researchers; most important journals; and comparisons with other surveys and with citation data. (LRW)

Discusses synchronous impact factors and theoretical models derived from observations based on "Science Citation Index", and presents an exception to the general rules based on data from the "Chinese Science Citation Database". Considers that the observed discrepancies could be statistical fluctuations of the basic…

Reports the results of a study that analyzed citations from 140 journals and 148 monographs in social science fields. Data presented in the article's 10 tables include date distributions, forms of material cited, subject distributions, countries of publication cited, and rank order of journals cited. (JD)

Argues that the difficulties of identifying and estimating the size of any pools of citable items are so great that comparisons of citation counts are rarely valid, and that the relationship between the value of a work and its citation can only be assessed by careful study of the citing paper. (four references) (CLB)

Argues for precision (consistency) in citing, proposing an approach to citation analysis that ranks citation-signallers according to usefulness. Suggests that it is misguided to classify citation-signallers by the nature of the motivations inferred to underlie their use. (JKP)

The reciprocal relationship between bibliographic references and citations in the context of the scholarly communication system is examined. Semiotic analysis of referencing behaviors and citation counting reveals the complexity of prevailing sign systems and associated symbolic practices. (Author)

The research reported suggests some ways in which economists could help themselves by rationalizing their literature, making better use of the bibliographic tools in existence and improving these tools. Ways librarians could do more to assist their readers are specified. (10 references) (Author/NH)
