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

Objectives

This study describes the literature of hospital pharmacy and identifies the journals most commonly cited by authors in the field, the publication types most frequently cited, the age of citations, and the indexing access to core journals. The study also looks at differing citation practices between journals with a wide audience compared to a national journal with a focus on regional issues and trends in the field.

Method

Cited references from five discipline-specific source journals were collected and analyzed for publication type and age. Two sets were created for comparison. Bradford''s Law of Scattering was applied to both sets to determine the most frequently cited journals.

Results

Three-quarters of all cited items were published within the last 10 years (71%), and journal articles were the most heavily cited publication type (n=65,760, 87%). Citation analysis revealed 26 journal titles in Zone 1, 177 journal titles in Zone 2, and the remaining were scattered across 3,886 titles. Analysis of a national journal revealed Zone 1 comprised 9 titles. Comparison of the 2 sets revealed that Zone 1 titles overlapped, with the exception of 2 titles that were geographically focused in the national title.

Conclusion

Hospital pharmacy literature draws heavily from its own discipline-specific sources but equally from core general and specialty medical journals. Indexing of cited journals is complete in PubMed and EMBASE but lacking in International Pharmaceutical Abstracts. Gray literature is a significant information source in the field.  相似文献

Publications of the faculty of the University of Mississippi's School of Business were examined for a citation analysis. The following data were collected: journals cited, which publishers’ journals were cited, age of the citations, and the Library of Congress classification range cited. The results were analyzed by the business school as a whole and by the four major departments in the college: Finance, Management, Management Information Systems/Production Operations Management, and Marketing. The study was undertaken to gain a better understanding of the local faculty researchers’ needs, to examine how the library supports their needs, and to compare the local results with the metaresearch focused on specific subject or journal.  相似文献

We analyzed serial citations in 72 marine biology master's theses as well as the ranking data of aquatic science serials from six global serial citation metrics, to assess serial use by marine biology graduate students from two perspectives. From 1,035 unique serials, a core of 123 titles was identified and evaluated for access. Citation ages averaged 13.5 years, with 27% of serial citations dated prior to 1996. Students cited serials from disciplines beyond marine biology, demonstrating broad title dispersion compared to several other studies. Recommendations are offered for future investigation to develop a stronger understanding of graduate students’ use of the library's serial collection.  相似文献

Aim:The purpose of this study is to identify and describe the citing behavior of geomatics postgraduate students at the Wuhan University in China. These students constitute one of the main user groups of Wuhan University Library and the analysis of their use of literature (through the means of citation analysis) can yield valuable insights against which to benchmark and inform collection development policy and other services at the Information Technology Library (ITL) at Wuhan University.Design/methodology/approach:In this project, 9317 citations in 21 PhD and 180 MSc theses submitted at the Wuhan University in the years of 1988, 1996, and 2004 were analyzed. All cited materials were divided by output format (monographs, proceedings, journal articles) and the more in-depth analysis was conducted for all cited journals. The following characteristics of the cited journal literature were analyzed: subject, age, language, and dispersion of journal titles.Findings:An increased use of journal literature in bibliographies of geomatics theses was observed over time. A trend to increase citations to international conference proceedings was also noted as well as a trend to cite more journals in disciplines other than surveying and mapping. It was also noted that, over time, citations to documents in languages other than Chinese and English have significantly decreased (in some cases, disappeared). Large dispersion among the most frequently cited journals in different time periods (only 25% of titles were repeated in 1988, 1996, and 2004 top ranking journal lists) was also noted. It was also noted that the core of geomatics literature is expanding (it now takes 42% of journal titles to cover 80% of all citations).Practical implications:By analyzing citation patterns of the graduate students of geomatics in China, we can track the developments and changes within that discipline in China and can compare these trends internationally (e.g. increased role of a journal, the importance of conference proceedings, domination of the English-language sources, dispersion of journal literature, and increasing multidisciplinarity of the discipline). The techniques and methods used in this study can be replicated to study other disciplines. Also, it is hoped that the findings of this research will inform collection development planning, development of reference services, and information literacy training.  相似文献

This article reports a librarian's collection development efforts to support her institution's first independent doctoral degree (Ed.D., Educational Leadership) via a citation analysis comparing information usage by education doctorate dissertation authors from six peer institutions nationally. This analysis is part of a long-term examination of library collection use among California State University, Long Beach (CSULB) doctoral students. Key findings include the relative young age among the information resources in educational leadership, which resource formats were cited, what serial titles were cited the most, and where they are available electronically. The ultimate aim is the creation of an essential collection in the subject discipline.  相似文献

Today's managers of library journal collection budgets experience pressures from shrinking resource allocations and rising costs. Consequently, they seek ways to assess the value of their collections in relation to user needs. This study at Montana State University seeks to understand what resources users (both faculty and graduate students) are citing in their research, the breadth of the information cited that is provided by the Library, how the Library's proactive and reactive efforts might influence user satisfaction with the information resources provided, and how user perceptions align and differ from information realities. It takes a unique approach by comparing LibQual+® survey results and faculty and graduate student citation behaviors.  相似文献

This article investigates the importance of journal titles in the area of Management and Economics at the University of Lethbridge in southern Alberta, Canada. Not wanting to rely solely on usage data, the author undertook a citation analysis to see which journals were most frequently published in by the university's authors. The results showed that usage data does not tell the whole story when it comes to a journal's importance to an institution. The analysis also illuminated publishers providing journals which were most frequently used.  相似文献

This study, conducted at the Indiana University School of Dentistry Library using citation analysis, examined graduate dental student theses citations to determine the nature of materials cited, journal ownership, journal citation frequency, and citation age distribution. The results were compared to other scientific discipline citation analyses. Study results indicated that for the period studied, masters dental students, like medical and science students, cited recently published scholarly dental journal literature. The majority of the journals cited were owned by Indiana University system libraries. Areas for further research include faculty resource usage, e-journal impact, and interdisciplinary resource use.  相似文献

Successfully connecting users to content in an online environment demands a high level of accuracy in the information eco-system. However, journal titles change names and International Standard Serial Numbers (ISSNs). When publishers, subject indexes, link resolvers, or other parties involved in connecting users to content fail to accurately represent the original details of cited articles, links fail, content becomes inaccessible except to very accomplished and determined librarians, and users become frustrated. The PIE-J (Presentation and Identification of E-Journals) offers a simple and common-sense set of recommended practices and guidelines for publishers and content providers to follow to standardize the presentation and identification of e-journal content.  相似文献

Objective:This study aims to identify the core journals cited in the health care management literature and to determine their coverage in the foremost bibliographic databases used by the discipline.Methods:Using the methodology outlined by the Medical Library Association''s Nursing and Allied Health Resource Section (NAHRS) protocol for “Mapping the Literature of Nursing and Allied Health Professions,” this study updates an earlier study published in 2007. Cited references from articles published in a three-year range (2016–2018) were collected from five health care management journals. Using Bradford''s Law of Scattering, cited journal titles were tabulated and ranked according to the number of times cited. Eleven databases were used to determine coverage of the most highly cited journal titles for all source journals, as well as for a subset of practitioner-oriented journals.Results:The most highly cited sources were journals, followed by government documents, Internet resources, books, and miscellaneous resources. The databases with the most complete coverage of Zone 1 and 2 were Scopus, Web of Science Core Collection, and PubMed, while the worst performing databases were Health Business Elite, ABI/Inform, and Business Source Complete.Conclusions:The literature of health care management has expanded rapidly in the last decade, with cumulative citations increasing by 76.6% and the number of cited journal titles increasing by nearly 70% since the original study. Coverage of the core journals in popular databases remains high, although specialized health care management and business databases did not perform as well as general or biomedical databases.  相似文献

ABSTRACT

This study examines 17,138 citations in 358 journal articles published in the United States in the field of international relations (IR). The United Nations accounts for 282 (32.2%) of the 877 references to information resources of intergovernmental organizations (IGOs), and its publications were cited more than twice as often as those of both the European Union (EU) or World Bank. This dominance is only partly based on the UN's importance as an object of research: though only 15 (4.2%) of the selected articles deal extensively with the United Nations, its publications were cited in 79 (22.1%). The EU, by comparison, is the subject of 37 articles, but its publications were cited in only 36 (10.1%). This demonstrates the relevance of UN information resources to a broad range of topics in IR.  相似文献

This paper provides an evidence-based assessment of the University of Arkansas Libraries' collections to determine whether they are adequate to support the research and teaching needs of the marketing department. Specifically, it determined where the marketing faculty published, the characteristics of their publications, and the characteristics of their cited references. The study found that the faculty cited more recent literature and a prevalence of journal articles in their cited references. The results also demonstrate the preference of marketing faculty to work in small groups consisting of two to four collaborators.  相似文献

The major purpose of this study was to identify and assess indexing coverage of core journals in cytotechnology. It was part of a larger project sponsored by the Nursing and Allied Health Resources Section of the Medical Library Association to map the literature of allied health. Three representative journals in cytotechnology were selected and subjected to citation analysis to determine what journals, other publication types, and years were cited and how often. Bradford's Law of Scattering was applied to the resulting list of cited journals to identify core titles in the discipline, and five indexes were searched to assess coverage of these core titles. Results indicated that the cytotechnology journal literature had a small core but wide dispersion: one third of the 21,021 journal citations appeared in only 3 titles; another third appeared in an additional 26 titles; the remaining third were scattered in 1,069 different titles. Science Citation Index Expanded rated highest in indexing coverage of the core titles, followed by MEDLINE, EMBASE/Excerpta Medica, HealthSTAR, and Cumulative Index to Nursing and Allied Health Literature (CINAHL). The study's results also showed that journals were the predominantly cited format and that citing authors relied strongly on more recent literature.  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

This paper explores a new indicator of journal citation impact, denoted as source normalized impact per paper (SNIP). It measures a journal's contextual citation impact, taking into account characteristics of its properly defined subject field, especially the frequency at which authors cite other papers in their reference lists, the rapidity of maturing of citation impact, and the extent to which a database used for the assessment covers the field's literature. It further develops Eugene Garfield's notions of a field's ‘citation potential’ defined as the average length of references lists in a field and determining the probability of being cited, and the need in fair performance assessments to correct for differences between subject fields. A journal's subject field is defined as the set of papers citing that journal. SNIP is defined as the ratio of the journal's citation count per paper and the citation potential in its subject field. It aims to allow direct comparison of sources in different subject fields. Citation potential is shown to vary not only between journal subject categories – groupings of journals sharing a research field – or disciplines (e.g., journals in mathematics, engineering and social sciences tend to have lower values than titles in life sciences), but also between journals within the same subject category. For instance, basic journals tend to show higher citation potentials than applied or clinical journals, and journals covering emerging topics higher than periodicals in classical subjects or more general journals. SNIP corrects for such differences. Its strengths and limitations are critically discussed, and suggestions are made for further research. All empirical results are derived from Elsevier's Scopus.  相似文献
