- Abstract
- Citations support the communication of specialist knowledge by allowing authors and readers to make specific selections in several contexts at the same time. In the interactions between the social network of authors and the network of their reflexive communications, a sub textual code of communication with a distributed character has emerged. Citation analysis reflects on citation practices. Reference lists are aggregated in scientometric analysis using one of the available contexts to reduce the complexity: geometrical representations of dynamic operations are reflected in corresponding theories of citation. The specific contexts represented in the modern citation can be deconstructed from the perspective of the cultural evolution of scientific communication

- Abstract
- Citation analysis has long been used by librarians as an important tool of collection development and the advent of Internet technology and especially the WWW adds a new facet to the role played by citation analysis. One of the reasons why librarians create WWW homepages is to provide users with further sources of interest or reference and to do this libraries include links from their own homepages to other information sources. Reports current research on the analysis of WWW pages as an introduction to an examination of the homepages of 25 art libraries to determine what sites are most often included. The types of linked sites are analyzed based on 3 criteria: location, focus and evidence that the link was evaluated before the connection was establisheds

- Abstract
- University librarians continue to face the difficult task of determining which journals remain crucial for their collections during these times of static financial resources and escalating journal costs. One evaluative tool, Journal Citation Reports (JCR), recently has become available on CD-ROM, making it simpler for librarians to use its citation data as input for ranking journals. But many librarians remain unconvinced that the global citation data from the JCR bears enough correspondence to their local situation to be useful. In this project, I explore the correlation between global citation data available from JCR with local citation data generated specifically for the University of British Columbia, for 20 subject fields in the sciences and social sciences. The significant correlations obtained in this study suggest that large research-oriented university libraries could consider substituting global citation data for local citation data when evaluating their journals, with certain cautions.

- Abstract
- Describes how a representative sample of librarians was surveyed to carry out a comparative evaluation of selected journals in library and information science. Respondents were asked to rate each journal on a scale from poor to outstanding (0-10), in terms of their visibility and the quality of articles they publish. Such evaluation should assist librarians in journal selection and in determining the quality of journals to which they send their research papers for publication. Reports the findings of the survey which discovered that some journals such as Library Waves, Assistant Librarian and Library Journal get low ratings because of low visibility and irregular publication. Others such as African Journal of Library Archives and Information Science and Journal of Information Science are rated highly because of familiarity and accessibility. Argues that the results of the study should help librarians determine the quality of journals and will subsequently enhance their utilization and subscription.
