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 2008 Meier and Conkling first tested Google Scholar's coverage of the engineering literature against citations gathered from the Compendex database. Since that time, other studies have used the same methodology and found improvement in Google Scholar's coverage. This study uses engineering dissertations from Proquest Dissertations & Theses to create a data set of citations for the comparison of fee-based databases, Compendex and Scopus, against Google Scholar. From 1950 to 2017 Google Scholar outperformed both Compendex and Scopus in discoverability of citations in nine engineering subjects. These results have implications for collection management and information literacy program planning for librarians. 相似文献

The impact of monographs in a vertebrate zoology collection on the scientific literature was assessed using a randomly selected sample (52 monographs), Science Citation Index and a statistical package. Characterstics of the monographs considered were: copyright date, circulation, citation frequency and subdiscipline (ichthyology, herpetology, ornithology, mammalogy). Citing references were dispersed among journals in a wide array of disciplines. A few monographs proved to be very highly cited (one being cited nearly 600 times), and so generated the majority of the database of 2,971 citations. The ichthyology monographs generated the broadest subject dispersion among citing references. The herpetology collection is less active than are the others in terms of circulation and current citation frequency. The sample has been generating an ever increasing share of the citations in the Science Citation Index. A method that applies citation analysis to the evaluation of monograph collections is outlined. 相似文献

Library and information science (LIS) dissertations cite a wide variety of literature, reflecting the interdisciplinary nature of the field. A review of 76 LIS dissertations was undertaken to determine whether the disciplinary background of the dissertation adviser influences the citing behaviors of the dissertation author. Of the 76 dissertations, 38 were advised by individuals with a disciplinary background in LIS and 38 were advised by individuals with a disciplinary background outside of LIS. The Library of Congress subclass for each citation was determined according the venue of publication. The most cited authors overall and by each group were determined, as well as the percentage of citations to LIS literature over time. LIS-advised dissertations were found to have cited a wide variety of literature. The percentage of citations in LIS-advised dissertations to LIS literature has declined from a peak of 59% to 21%. Citations to the most-cited authors in each group were largely exclusive to the LIS-advised dissertations, and nonLIS-advised dissertations generally do not appear to cite the same bodies of academic literature. 相似文献

The purpose of this study was to determine if a computerized commercial selective dissemination of information service could contribute to the services offered to the patrons of a specific medical library who were already participating in a manual selective dissemination of information service. The citations generated by the two services were contrasted on the basis of literature coverage, timeliness of retrieval, and relevancy of output. Eighty-four percent of the discrete citations retrieved were from 664 periodicals subscribed to by both services. Only 16 percent of the total of 1,387 discrete citations were produced by both services. The manual service was more timely; and, although it produced fewer citations, a higher percentage of these were relevant. Numerically, a total of 346 useful citations were recovered by the manual service and 379 from the commercial service. It appears, therefore, that a computerized commercial SDI service could contribute to the services offered to the medical scientists participating in a manual SDI service. 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

OBJECTIVE: To study the circulation of monographs during the first three years of shelf life at an academic health sciences library. METHOD: A record was kept of monographs added to the circulating collection from mid-1994 to mid-1995. After three years, each monograph was located and the number of times it circulated during the first, second, and third year of shelf life determined by counting checkout stamps on the circulation slip. RESULTS: Of the 1,958 monographs studied, 1,674 had complete data for the first three years of shelf life. Of those 1,674 titles, 81.48% circulated at least once. A total of 7,659 circulations were recorded; 38.69% occurred in the first year of shelf life, 32.37% in the second year, and 28.95% in the third year. The data did not fit the well-known 80/20 rule. Instead, approximately 38% of monographs accounted for 80% of circulation. A small percentage, 2.21%, of monographs accounted for a substantial percentage of circulation, 21.84%. CONCLUSIONS: A large percentage of the monographs circulated and use did not decline sharply with age within the first three years of shelf life, indicating a high demand for monographs at this academic health sciences library. These results, combined with the findings of earlier studies, suggested two possibilities. First, academic health sciences libraries might exhibit use of a higher percentage of monograph acquisitions than other types of libraries; or, second, a low monograph-to-user ratio might result in a higher percentage of monographs being used. Perhaps both factors contributed to the results found in this study. Further investigation would be needed to determine the extent to which library type and monograph-to-user ratio influenced monograph use. 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 study examines how the social sciences' debate between qualitative and quantitative methods is reflected in the citation patterns of sociology journal articles. Citation analysis revealed that quantitative articles were more likely to cite journal articles than monographs, while qualitative articles were more likely to cite monographs than journals. Quantitative articles cited other articles from their own quantitative-dominated journals but virtually excluded citations to articles from qualitative journals, while qualitative articles cited articles from the quantitative-dominated journals as well as their own qualitative-specialized journals. Discussion and conclusions include this study's implications for library collection development. 相似文献
