Abstract
By examining the references of research and specific topic articles of JASIST, this study explored the disciplines and subjects relating to information science. According to the website of JASIST, there are 1,341 research and specific topic articles with 51,359 references during the period of 1998 to 2008. Since journal articles and monographs are cited by JASIST most, the citation analysis of this study will focus on these two document type references only. Firstly, this study applies the Bradford's Law and Bradford-Zipf's Law to identify the core journals which were cited by JASIST. Then, search the classification number and subject categories of WorldCat and Ulrichsweb.com and also the descriptors of LISA to analyze cited references. Followings are the research results: 一、JASIS(T) published 2,031 articles from 1998 to 2008, with an average number of 185 per year. Among them, 1,341articles are research and specific topic paper, contributing 66.02% of all published items. Journal articles and monographs are two most cited reference for research and specific topic articles. 二、JASIS(T) has cited a total of 27,115 journal literature, distributing over 2,994 journals. By applying the Bradford's Law, there are four core journals cited by JASIS(T). However, by applying the Bradford-Zipf's Law, there appears to be ten core journals. The journal that had been cited the most is JASIS(T) itself (17.47% of all citations), suggesting JASIS(T)'s self-citation is obvious. 三、For journals cited by the JASIS(T), bibliography. library science. information resources (general), science, and social sciences are the three most cited disciplines. The most commonly cited subjects, which identified from WorldCat and Ulrichsweb.com, are information science, information technology, information storage and retrieval systems, library science, and science. However, searching, online information retrieval, information work, subject indexing, and information storage and retrieval, which searched from LISA, are the most cited descriptors of the library and information science journals cited by JASIS(T). 四、JASIS(T) has cited a total of 27,115 monograph literature, distributing over 5,565 books. Introduction to Modern Information Retrieval written by Salton & McGill was cited the most. Three of the top ten cited monographs are written by Salton. It may suggest that Salton is one of the most influential authors in the field of information science. In addition, 91% of the books cited by JASIS(T) less than 3 times indicates that JASIS(T) cited monographs diversified. 五、For monographs cited by the JASIS(T), science, social sciences, and bibliography. library science. information resources (general) are the three most cited disciplines. The most commonly cited subjects, which identified from WorldCat and Ulrichsweb.com, are information storage and retrieval systems, human-computer interaction, information retrieval, information science, and cognition. 六、From comprehensive analysis on the discipline of the journals and monographs cited by JASIS(T), it can be found that bibliography. library science. information resources (general), science, and social sciences are the most cited disciplines by JASIS(T). In the other words, these three disciplines are not only the most influential resources, but also are closely related to information science.
