The purpose of this article is to describe the reasoning, methodology, and impact behind a semi-automated cataloging process for electronic theses and dissertations, and to explain the importance of the retention and addition of cataloger-created metadata. The authors explain an automated process that is initiated by ProQuest and student (author) entered data, and through the addition of metadata by catalogers, including the subject headings, classification number, and so on. The study includes a survey of the public service librarians’ perceived usefulness of the cataloger- and ProQuest-generated metadata to describe theses and dissertations.  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

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

Given the thousands of theses and dissertations (TDs) that are produced each year, and their role in advancing their disciplines, it is well worth disseminating them as widely as possible. A great leap forward in increasing TD distribution has been the electronic theses and dissertations (ETDs) movement. ETD information in catalogs provides valuable basic access, especially when bibliographic records are contributed to large databases. While these bibliographic records can be created automatically by harvesting author-supplied metadata from ETDs, for fuller access, cataloger mediation is needed to remove errors and numeric entities; plus name authority control. Fullest access entails subject analysis.  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

Dissertations can be the single most important scholarly outputs of junior researchers. Whilst sets of journal articles are often evaluated with the help of citation counts from the Web of Science or Scopus, these do not index dissertations and so their impact is hard to assess. In response, this article introduces a new multistage method to extract Google Scholar citation counts for large collections of dissertations from repositories indexed by Google. The method was used to extract Google Scholar citation counts for 77,884 American doctoral dissertations from 2013 to 2017 via ProQuest, with a precision of over 95%. Some ProQuest dissertations that were dual indexed with other repositories could not be retrieved with ProQuest-specific searches but could be found with Google Scholar searches of the other repositories. The Google Scholar citation counts were then compared with Mendeley reader counts, a known source of scholarly-like impact data. A fifth of the dissertations had at least one citation recorded in Google Scholar and slightly fewer had at least one Mendeley reader. Based on numerical comparisons, the Mendeley reader counts seem to be more useful for impact assessment purposes for dissertations that are less than two years old, whilst Google Scholar citations are more useful for older dissertations, especially in social sciences, arts and humanities. Google Scholar citation counts may reflect a more scholarly type of impact than that of Mendeley reader counts because dissertations attract a substantial minority of their citations from other dissertations. In summary, the new method now makes it possible for research funders, institutions and others to systematically evaluate the impact of dissertations, although additional Google Scholar queries for other online repositories are needed to ensure comprehensive coverage.  相似文献

Abstract

The researchers extracted a disproportionate stratified random sample from 40?years of thesis bibliographic records at Concordia University in Montreal, Quebec. Match rates for thesis authors in the LC/NACO Name Authority File and in Canadiana Authorities were examined. ProQuest digitization of older theses, the creation of an institutional repository, the move to electronic theses and dissertations in 2011, and the implementation of vendor-assisted authority control in 2017 impacted bibliographic records. In addition to the dearth of matches in general, results uncovered false matches and significant changes to Library and Archives Canada thesis authority control practices over the 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

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

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

博、硕士学位论文具有重要的学术价值,而国内外学术界和出版界对于学位论文内容的再出版问题持有不同的观点。通过调研国内外学术界和出版界发现,国外绝大多数高校和出版机构认为学位论文并不算作先前出版物,基于学位论文内容再出版的稿件能否被接受,关键在于稿件的质量,另外,根据不同出版机构及受众特点对学位论文进行修改是非常必要的。国内相关研究尚待深入,多数研究人员和期刊编辑认为,学位论文因学术价值的特殊性,其析出内容的再出版应得到更加理性和全面的分析。面对纷繁乱象,建议我国有关部门应尽快出台相关规定,出版机构阐明学位论文与先前出版物的关系,以及对于学位论文析出内容再出版的要求,以适应网络出版日益普及的新形势。  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

This work takes advantage of the current status of the development of electronic theses and dissertations (ETDs) at the University of Louisville to reexamine a previous study that compared ETD and non-ETD producing authors' use of the professional literature. As with the previous study, this effort found no noticeable difference in the two groups of doctoral students' referencing behavior. This review of 100 dissertations and their 13,926 references confirmed the previous work's conclusions that doctoral students' publication format is not reflective of their library research. These findings suggest that librarians need not amend their efforts in response to academia's on-going development of ETDs and that differences between ETD and non-ETD authors are unrelated to their utilization of library resources.  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
