Citation Autobiography: An Investigation of ISI Database Coverage in Determining Author Citedness
(Association of College & Research Libraries, 2004-03) Nisonger, Thomas E.
This article presents a case study investigating the coverage complete- ness of the Institute for Scientific Information’s citation data for specific authors, based on analysis of this author’s lifetime citation record, which was compiled through the ISI database, searching the literature for nearly fifteen years, and through various Web search engines. It was found that (with self-citations disregarded) the ISI captured 28.8 percent of the total citations, 42.2 percent of print citations, 20.3 percent of citations from outside the United States, and 2.3 percent of non-English citations. The definition and classification of Web citations are discussed. It is suggested that librarians and faculty should not rely solely on ISI author citation counts, especially when demonstration of international impact is important.
The Perception of Library and Information Science Journals by LIS Education Deans and ARL Library Directors: A Replication of the Kohl-Davis Study
(Association of College & Research Libraries, 2005-07) Nisonger, Thomas E.; Davis, Charles H.
Analyzing the collective opinion of presumed experts, often termed a per- ception study, is a frequently used approach for rating journals or evaluating education programs. Replicating the 1985 Kohl–Davis study, seventy-one library and information science (LIS) journals are ranked according to their mean rating on a 1 to 5 ordinal scale by deans of ALA-accredited educa- tion programs and by the directors of ARL libraries (surveyed during the summer of 2003). Comparison of the results with the 1985 study found considerable continuity in journal perceptions over the past two decades, but more so by directors than deans. A weak to moderate correlation was found between deans’ ratings and Journal Citation Reports citation scores, whereas the correlations between directors’ perceptions and citation data were weak to nonexistent. The ﬁndings conﬁrm a hierarchy of prestige among LIS journals, but the hierarchical order differs somewhat between deans and directors.
The Relationship between International Editorial Board Composition and Citation Measures in Political Science, Business, and Genetics Journals
(Springer Verlag, 2002) Nisonger, Thomas E.
Three measures of international composition on journal editorial boards—the number of countries represented on the board, the number of international members, and the proportion of international board members—were correlated with impact factor and total citation data in the 1999 Journal Citation Reports for 153 business, political science, and genetics journals. With a few exceptions the relationship between international editorial board composition and citation measures was non-linear, leading to the conclusion that international membership on the editorial board can not generally be used as a marker of better journal quality. Yet further investigation is warranted due to positive correlations between some editorial board and citation measures for non-U.S. business and political science journals.
Use of Journal Citation Reports for Serials Management in Research Libraries: An Investigation of the Effect of Self-Citation on Journal Rankings in Library and Information Science and Genetics
(Association of College & Research Libraries, 2000-05) Nisonger, Thomas E.
This article explores the use of the Institute for Scientific Information’s Journal Citation Reports (JCR) for journal management in academic libraries. The advantages and disadvantages to using JCR citation data for journal management are outlined, and a literature review summa- rizes reported uses of these data by libraries and scholars. This study researches the impact of journal self-citation on JCR rankings of library and information science (LIS) and genetics journals. The 1994 rankings by impact factor and total citations received were recalculated with jour- nal self-citations removed; then the recalculated rankings were com- pared to the original rankings to analyze the effect of self-citations. It is concluded that librarians can use JCR data without correcting for jour- nal self-citation, although self-citations do exert a major effect on the rankings for a small number of journals.
