AbstractThe first and unique training centre in Library and Information Science (LIS) in Benin has been training students since 1982. Ten years after the introduction of Internet in the country, students may have been aware of the importance and the richness of its resources. To what extent do students use Internet-based resources? How do citations to Internet-based resources vary in students’ works over years? This study covers especially LIS students’ dissertations. The results show that the percentage of Internet-based resources cited in dissertations was very low until 2001. Even if the trend line shows an increase starting from 2002, Internet-based resources are very rare in the dissertations (less than 10%). A few students give references to the maximum of Internet-based resources. 相似文献

A citation analysis of 61 library science and information science dissertations revealed some interesting publication patterns. About 80% of the citations are to single authors, and as in analyses of periodical literature, males are cited more than females overall (about 61% to 39%). In dissertations related to school or public libraries, the male/female distribution is less disparate; for studies in academic or special libraries two thirds of the authors are male, and male authorship is 75% when only information science dissertations are analyzed. Journal articles are cited more than books, book chapters, proceedings, theses, and other formats with College & Research Libraries and Journal of the American Society for Information Science used most. Library and information science is impacted by several other disciplines, primarily education, computer science, health/medicine, psychology, communications, and business. Authors cited in dissertations represent a somewhat less parochial list in terms of citing U.S. publications than authors cited in studies analyzing journal citations; over half of all works cited were published within the last 10 years. 相似文献

This paper evaluates the literature guarantee for Folklore graduate students based on their dissertations at Beijing Normal University (BNU) Library. First, it investigates related works concerning literature guarantees. Researchers collected 72 master's and 47 doctoral students' dissertations between 2011 and 2014. By building a literature guarantee hierarchy for monographs and periodicals, this study maps citations to the library collection to quantify the collection status. Findings demonstrate that nearly 81% of monograph citations, which is slightly less than periodical citations (nearly 90%), are owned by the library. In frequently cited literature, the percentage rises to 90% for both monographs and periodicals. Moreover, the literature guarantee percentage of electronic monographs (74.8%) and periodicals (87.6%) are both higher than paper editions. This study also provides suggestions to improve the literature guarantee. Finally, it points out some limitations and future direction. 相似文献

This article analyzes the bibliometric features (the number of pages, completion years, the fields of subject, the number of citations, and their distribution by types of sources and years) of 100 theses and dissertations completed at the Department of Librarianship of Hacettepe University between 1974 and 2002. Almost a quarter (24%) of all dissertations were on university libraries, followed by public libraries (9%). Doctoral dissertations were, on average, twice as long as master's theses and contained 2.5 times more citations. Monographs received more citations (50%) than journal articles did (42%). Recently completed theses and dissertations contained more citations to electronic publications. Fourteen (or 3.2% of all) journal titles (including Türk Kütüphaneciliği, College & Research Libraries, and Journal of the American Society for Information Science) received almost half (48.9%) of all citations. Eighty percent of journal titles were cited infrequently. No correlation was found between the frequency of citations of the most frequently cited journals and their impact factors. Cited journal titles in master's and doctoral theses and dissertations overlapped significantly. Similarly, journal titles cited in dissertations also overlapped significantly with those that were cited in the journal articles published in the professional literature. The distribution of citations to foreign journal titles fit Bradford's Law of Scattering. The mean half-life of all cited sources was 9 years. Sources cited in master's dissertations were relatively more current. Single authorship was the norm in cited resources. Coupled with in-library use data, findings of the present study can be used to identify the core journal titles in librarianship as well as to evaluate the existing library collections to decide which journal titles to keep, discard, or relegate to off-site storage areas. 相似文献

Connecting academic libraries to the higher education environment is crucial for demonstrating the impact of libraries on student success. The purpose of this study is to examine the information transfer between the disciplines of library and information science (LIS) and higher education in order to evaluate the influence of ideas between the two disciplines. Information transfer was analyzed in 39 articles focused on the library's contributions to student success by examining the cited references, the author and collaborator affiliations, and the forward citations. The findings from the cited reference analysis suggest that LIS is borrowing concepts and methods through citations from the discipline of education. Authorship affiliations showed that some non-LIS authors are publishing in the field of LIS and that LIS authors are collaborating with non-LIS authors. Finally, based on the forward citations, other disciplines are rarely citing LIS research about student success. This article's findings highlight the need to consider research and collaborators outside of the LIS field when researching the library's contribution to student success. 相似文献

Using 17 open-access journals published without interruption between 2000 and 2004 in the field of library and information science, this study compares the pattern of cited/citing hyperlinked references of Web-based scholarly electronic articles under various citation ranges in terms of language, file format, source and top-level domain. While the patterns of cited references were manually examined by counting the live hyperlinked-cited references, the patterns of citing references were examined by using the cited by tag in Google Scholar. The analysis indicates that although language, top-level domain, and file format of citations did not differ significantly for articles under different citation ranges, sources of citation differed significantly for articles in different citation ranges. Articles with fewer citations mostly cite less-scholarly sources such as Web pages, whereas articles with a higher number of citations mostly cite scholarly sources such as journal articles, etc. The findings suggest that 8 out of 17 OA journals in LIS have significant research impact in the scholarly communication process. 相似文献

Clinical psychology has received little attention as a subject in health sciences library collections. This study seeks to demonstrate the relative importance of the monographic literature to clinical psychology through the examination of citations in graduate student theses and dissertations at the Fordham Health Sciences Library, Wright State University. Dissertations and theses were sampled randomly; citations were classified by format, counted, and subjected to statistical analysis. Books and book chapters together account for 35% of the citations in clinical psychology dissertations, 25% in nursing theses, and 8% in biomedical sciences theses and dissertations. Analysis of variance indicates that the citations in dissertations and theses in the three areas differ significantly (F = 162.2 with 2 and 253 degrees of freedom, P = 0.0001). Dissertations and theses in biomedical sciences and nursing theses both cite significantly more journals per book than the dissertations in clinical psychology. These results support the hypothesis that users of clinical psychology literature rely more heavily on books than many other users of a health sciences library. Problems with using citation analyses in a single subject to determine a serials to monographs ratio for a health sciences library are pointed out. 相似文献

Study investigates the availability, persistence and half life of URL citations cited in two Indian LIS journals articles published between 2002 and 2010. This study also investigates how researchers can resurrect lapsed URL citations cited in research articles, using Wayback machine. A total of 1290 URLs cited in 472 research articles published in Indian LIS journals spanning a period of 9 years (2002–2010) were extracted. Study found that only 18.91% (1290 out of 6820) of URLs cited in these journal articles. 39.84% of URL citations were not accessible and remaining 60.15% of URL citations were still accessible. The HTTP 404 error message-“page not found” was the overwhelming message encountered and represented 54.86% of all HTTP error messages. However 51.06% URLs were recovered from HTTP 404 error message. Study also noticed that the half-life of URL citations was increased from 6.33 years to 13.85 years after recovering missing URLs from Wayback machine. 相似文献

We investigate the contributions of scientific software to library and information science (LIS) research using a sample of 572 English language articles published in 13 journals in 2008, 2011, 2014, and 2017. In particular, we examine the use and citation of software freely available for academic use in the LIS literature; we also explore the extent to which researchers follow software citation instructions provided by software developers. Twenty-seven percent of the LIS journal articles in our sample explicitly mention and use software. Yet although LIS researchers are becoming increasingly reliant on software that is freely available for academic use, many still fail to include formal citations of such software in their publications. We also find that a substantial proportion of researchers, when documenting software use, do not cite the software in the manner recommended by its developers. 相似文献

Dissertation advising is an important form of mentoring. To investigate the impact of dissertation advising over time, advisor and committee member names were collected for 2400 dissertations completed over a 40-year period (1964–2004) in 32 North American information and library science schools. Several mentoring impact metrics are reported for a subset of the data, including the number of dissertations advised, the number of dissertation committees served on, the ratio of advising to committee membership, and the fractional “mpact” that weights advising and committee membership. The subset consists of data for six schools that produced at least three dozen dissertations and for which complete data is available. The data and resulting “mpact” metrics offer new ways to assess faculty impact and to investigate the nature and growth of a field. 相似文献

The preferences of the authors of Chinese library and information science (LIS) journal articles in citing Internet sources were investigated using eight premium Chinese LIS journals from Chinese Social Sciences Citation Index (the observation group) and 10 journals in other disciplines (the control group) from the same database from 1999 to 2008. A total of 252,881 citations were analyzed in terms of count, domain name, and citing purposes. The results show that (a) in comparison to the disciplines in the control group, LIS articles in Chinese journals indicated a strong preference for citing Internet sources, and this preference is increasing; (b) LIS articles did not seem to discriminate against domain names when citing Internet sources; and (c) LIS articles cited more Internet sources as evidence to support research results and conclusions. Excessive dependency on Internet sources may raise concerns over the quality, research ethics, and credibility of research publications. Chinese LIS researchers should place more emphasis on the disadvantages of Internet sources as supporting material. Guidelines and criteria to help researchers, journal editors, students, and librarians assess information on the Web need to be developed. 相似文献

Scientific collaboration and endorsement are well-established research topics which utilize three kinds of methods: survey/questionnaire, bibliometrics, and complex network analysis. This paper combines topic modeling and path-finding algorithms to determine whether productive authors tend to collaborate with or cite researchers with the same or different interests, and whether highly cited authors tend to collaborate with or cite each other. Taking information retrieval as a test field, the results show that productive authors tend to directly coauthor with and closely cite colleagues sharing the same research interests; they do not generally collaborate directly with colleagues having different research topics, but instead directly or indirectly cite them; and highly cited authors do not generally coauthor with each other, but closely cite each other. 相似文献

This case study is a citation analysis of 56 PhD theses submitted in 2005 at Wuhan University (www.whu.edu.cn) in China. The authors analyzed 10,222 citations in theses in Library and Information Science, Biology, Photogrammetry and Remote Sensing, and Stomatology and reviewed and compared the characteristics of the literature cited in the four disciplines. The results revealed that in Biology and Stomatology mainly English language publications were cited whereas in the field of Library and Information Science, the cited literature came primarily from Chinese sources. In Photogrammetry and Remote Sensing, citations were almost evenly split between English and Chinese sources. An appendix with tables of the journal titles cited most frequently may be used to evaluate serial holdings and to serve as a guide for students preparing their theses. In addition, the implications for library collection development policies and other technical services are discussed. 相似文献

Research on publication and citation patterns generally focuses on prolific or highly cited authors or on highly ranked programs. This study investigates the work and influence of a cross-section of library and information science (LIS) researchers at various stages of their academic lives, using a random sample of faculty members at programs accredited by the American Library Association. The analysis shows that the number of publications increases steadily as faculty rank advances. Assistant professors publish more conference papers and fewer journal articles, a pattern that is reversed with associate and full professors. Researchers used Web of Science® and Google™ Scholar to determine the influence of the publications. Web of Science reported no citations for most LIS faculty publications. With its broader scope, Google Scholar located more citations and revealed that the works of professors are cited significantly more frequently than publications by assistant or associate professors. When faculty profiles are compared by type of program, faculty members at schools granting doctoral degrees publish significantly more than their counterparts at schools where there is no doctoral program or where the doctoral degree is offered jointly with other academic units. When the comparison is made across ranks, full professors publish significantly more than faculty members at other ranks. There is no significant difference between assistant and associate professors. 相似文献
