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

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 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

GOOGLE学术搜索工具及其在我馆的应用 总被引：2，自引：0，他引：2
分析了Google学术搜索在学术资源服务体系中的积极作用。Google学术搜索继承了Google的优点,吸引了大批用户。它基本上可以正确地甄别资源的学术性,在搜索的效果方面也有不错的表现,在弥补图书馆对公开获取资源的资源服务方面,起到很好的补充作用。但是也有不足之处。比如没有考虑用户的资源环境,不能很好地解决“合适版本”的问题,不能避免用户的无效链接现象。最后介绍了北京师范大学图书馆对Google学术搜索的理解和实际应用的做法。以及通过参加Library Link计划,将Google学术搜索成功纳入图书馆学术资源服务体系的成功案例。最后的统计数字说明Google学术搜索在该校起到了很好的资源服务作用。 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

Rhodes University mounted its first digital thesis on the World Wide Web in 1998 and became the first institution in Africa to do so. Since then, the number of available theses and dissertations has steadily increased as more students come to appreciate the importance of submitting digital files or their theses. Also, the university Senate has now made it mandatory for students to submit digital files of their theses and dessertations. In order to make electronic theses and dissertations (ETD) produced by tertiary institutions in Southern Africa readily available, universities in the Southern African region were invited to join in the ETD initiative. This would lead to the building of a digital library of theses and dissertations in the region. A few institutions have responded positively and, based on the adoption of our approach, have speedily gained approval of their governing bodies to embark on ETD projects. In addition, the South East Academic Libraries (SEALS), a library consortium of tertiary institutions in the Eastern Province of South Africa, is considering an ETD programme since this would promote collaboration between research programmes at separate universities/technikons by making research work visible and accessible via a network archive.It is, however, surprising that some institutional leaders appear not to have realized that the digital revolution makes it imperative for institutions to use digital and publishing technologies innovatively in the provision of information as well as in the preservation and dissemination of the institutions' intellectual property.The paper will review existing African theses and dissertation projects, including the Database of African Theses and Dissertations (DATAD) and the African Universities Dissertations Abstracts (AFUDA) projects, it will discuss the status of the Rhodes University project, responses from other institutions in the region and make suggestions for accelerated involvement of tertiary institutions in Africa, especially Southern Africa, in the international network of theses and dissertations. 相似文献
