A Review of: Gonzalez-Alcaide, Gregorio, Lourdes Castello-Cogolles, Carolina Navarro-Molina, et al. “Library and Information Science Research Areas: Analysis of Journal Articles in LISA.” Journal of the American Society for Information Science and Technology 59.1 (2008): 150-4. Objective – To provide an updated categorization of Library and Information Science (LIS) publications and to identify trends in LIS research. Design – Bibliometric study. Setting – The Library and Information Science Abstracts (LISA) database via the CSA Illumina interface. Subjects – 11,273 item records published from 2004-2005 and indexed in LISA. Methods – First, a search was set up to retrieve all records from 2004-2005, limited to peer review items (called “arbitrated works” by the authors (150)) and excluding book reviews. Second, thematic descriptor terms used for the records were identified. Frequency counts for descriptor term occurrence were compiled using Microsoft Access and Pajek software programs. From the results of this search, the top terms were analyzed using the Kamada-Kawai algorithm in order to eliminate descriptor term co-occurrence frequencies under 30. A cluster analysis was used to depict thematic foci for the remaining records, providing a co-word network that visually identified topic areas of most frequent publication. Conclusions were drawn from these findings, and recommendations for further research were provided. Main Results – The authors identified 18 “thematic research core fields” (152) clustered around three large categories, “World Wide Web”, “Education”, and “Libraries”, plus 12 additional peripheral categories, and provided a schematic of field interrelationships. Conclusion – Domains of greatest focus for research “continue to be of practical and applied nature,” (153) but include increased emphasis on the World Wide Web and communications technologies, as well as on user studies. A table of the most frequently occurring areas of research along with their top three descriptor terms is provided (Table 1, 152) (e.g., “World Wide Web” as the top area of research, with “online information retrieval” (268 occurrences), “searching” (132 occurrences), and “web sites” (115 occurrences)).
