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

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

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4.

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 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 effectiveness of periodicals indexed in the Readers' Guide to Periodical Literature was analyzed and related to obsolescence rates of scientif/research-oriented journals. Citations from 25 years of theses and dissertations found that most Readers' Guide titles were not used for research purposes. The bulk of citations occurred within 5 years of an article's publication and clustered in the same small number of titles. Implications for retention of titles indexed in the Readers' Guide are discussed. Use per unit o f shelf space, cost of storage, plus the minimal research ualue of Readers' Guide items make them a prime target for cooperative storage efforts. 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

In an effort to measure in-house use of music periodicals, a citation study based on bibliographies in theses and dissertations was conducted at the Indiana University Music Library. A total of 256 titles were cited, but only 30% were cited more than once. While the periodical literature cited by musicologists has a low rate of obsolescence, the periodicals cited by theorists and educators becomes obsolete at a rapid rate, making the rate of obsolescence for the field as a whole, fairly high, unlike other subject areas in the humanities. 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

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

Many librarians perceive ProQuest’s Dissertations and Theses as the key resource for searching dissertations and theses. However, the Online Computer Library Center’s (OCLC’s) WorldCat also provides a means for locating electronic dissertations and theses. This study compared these two databases and found two key observations. First, both databases provided access to a similar number of citations. Second, WorldCat consistently had twice as many citations for which ProQuest had no records. WorldCat provides an important means of locating electronic theses and dissertations. 相似文献

Academic libraries are increasingly seeking ways to demonstrate their impact on student learning. Acknowledgments - formal statements of indebtedness – in graduate theses and dissertations provide a rather unexplored area for demonstrating impact of the academic library on student learning. This study uses quantitative and qualitative methods to characterize acknowledgments of the Texas A&M University Libraries (TAMU Libraries) in theses and dissertations, both overall and for three disciplines specifically: civil engineering, geography, and history. This study also searched for mentions of the TAMU Libraries throughout the entire body of theses and dissertations. Overall, acknowledgments to the TAMU Libraries in theses and dissertations were less than 1%, though acknowledgments were found in all three disciplines with over a quarter of the history theses and dissertations containing an acknowledgment to libraries. There was no statistically significant difference found between the numbers of acknowledgments in theses versus dissertations. Acknowledgments to the TAMU Libraries were found in the theses and dissertations of 28 different departments. Mentions to the TAMU Libraries – not necessarily a formal acknowledgment – were found throughout the text of theses and dissertations with most concentrated in the acknowledgment, method, and bibliography sections. 相似文献

The study investigated the extent of adoption of electronic theses and dissertations in university libraries in Nigeria. Data collection for the study was via online questionnaire. The study revealed that digitization of theses and dissertations started between 1980 and 1995. It was found that only a few university libraries have embraced digitization of theses and dissertations in Nigeria. Benefits of electronic theses and dissertations were identified as improving university ranking and visibility, increasing access to the theses and dissertations, saving space in the library, enabling others link to the work with persistent URLs, preserving the work for future generations, and saving costs for students. Challenges such as unstable internet connectivity, lack of funding, irregular power supply, lack of information technology personnel, absence of electronic theses and dissertations submission policy, and copyright issues were identified. It is hoped that the study might provide insights useful for librarians planning to embark on the digitization of theses and dissertations project. 相似文献

Objectives:
The research identified the publication types and ages most frequently cited in the infectious diseases literature and the most commonly cited journals.Methods:
From 2008–2010, 5,056 articles in 5 infectious diseases journals cited 166,650 items. Two random samples were drawn: one (n = 1,060) from the total set of citations and one (n = 1,060) from the citations to journal articles. For each sample citation, publication type and date, age of cited item, and inclusion of uniform resource locator (URL) were collected. For each item in the cited journal articles sample, journal title, publication date, and age of the cited article were collected. Bradford zones were used for further analysis.Results:
Journal articles (91%, n = 963) made up the bulk of cited items, followed by miscellaneous items (4.6%, n = 49). Dates of publication for cited items ranged from 1933–2010 (mean = 2001, mode = 2007). Over half (50.2%, n = 483) of cited journal articles were published within the previous 5 years. The journal article citations included 358 unique journal titles.Discussion:
The citations to current and older publications in a range of disciplines, heavy citation of journals, and citation of miscellaneous and government documents revealed the depth and breadth of resources needed for the study of infectious diseases.Highlights
- Literature on infectious diseases is multidisciplinary, encompassing medical specialties, public health, and the medical sciences.
- Infectious disease publications cite journal articles more than 90% of the time. Cited journal articles greatly range in age at citation: more than a quarter were over 10 years old.
- Infectious disease citation patterns resemble clinical medicine citation patterns more than public health citation patterns.
Implications
- Infectious disease professionals need access to general medicine titles as well as infectious disease, immunology, virology, microbiology, and public health literature.
- Librarians serving infectious disease researchers and practitioners should provide access to older materials, especially journal back files, to support the cyclical needs of their patrons.

A total of 7,149 references appearing in 253 source items (including books, book artiles, journal articles, and dissertations) in the field of American literature were analyzed. From the analysis lists of the most frequently cited periodical titles and book titles (both primary and secondary) were formulated. Since such a large number of titles is cited, the lists reveal relatively small clusters of frequently-cited materials and do not identify fringe areas. The results do point to areas for retrospective development of collections and indicate possibilities for cooperative collection and study of citation data. 相似文献

Objectives:
The purpose of this study was to identify (1) core journals in the literature of physical therapy, (2) currency of references cited in that literature, and (3) online databases providing the highest coverage rate of core journals.Method:
Data for each cited reference in each article of four source journals for three years were recorded, including type of literature, year of publication, and journal title. The journal titles were ranked in descending order according to the frequency of citations and divided into three zones using Bradford''s Law of Scattering. Four databases were analyzed for coverage rates of articles published in the Zone 1 and Zone 2 journals in 2007.Results:
Journal articles were the most frequently cited type of literature, with sixteen journals supplying one-third of the cited journal references. Physical Therapy was the most commonly cited title. There were more cited articles published from 2000 to 2007 than in any previous full decade. Of the databases analyzed, CINAHL provided the highest coverage rate for Zone 1 2007 publications.Conclusions:
Results were similar to a previous study, except for changes in the order of Zone 1 journals. Results can help physical therapists and librarians determine important journals in this discipline.Highlights
- More cited references were published in the last eight years studied than in any previous full decade.
- Physical Therapy, Archives of Physical Medicine and Rehabilitation (APMR), and Spine were the most frequently cited titles. Previous studies found APMR to be the most cited journal.
- CINAHL provided the highest coverage rate for the most commonly cited titles, with MEDLINE and EMBASE providing the best coverage for the next group of titles.
Implications
- Health sciences librarians and clinicians can use these results to identify important journals for developing collections and determining the need for access to back issues of journals.
- Multiple databases are needed for comprehensive coverage of the physical therapy discipline

The goal of this analysis was to obtain local citation behavior data on undergraduates researching history, political science, and sociology papers. The study found that students cited books and journals even with the availability of web sources; however, usage varied by subject. References to specific websites' domains also varied across subject area. Most of the top journal titles that students referenced were online and locally owned. Students cited a broader range of journal titles than predicted by the Law of Scattering and cited titles across a wide array of subject areas. This data helped identify potential gaps in the library's collection and services. 相似文献
