Abstract

Faculty publication databases or author bibliographies offer libraries an opportunity to provide services to users. Initially, these databases remained initiatives of special libraries in the health-sciences fields. Librarians used the publication information derived from these databases to compile lists for annual reports. However, the advent of new technologies, especially the Web, prompted numerous libraries to develop faculty publication databases for their institutions. The author conducted a survey of various listservs to discover the history and development of these databases. The results illustrate the popularity of Web-based faculty publication databases. The motivation for their creation varied, but most respondents emphasized the desire to highlight the research activities of their institutions. In addition, the content of materials included in the databases and the definition of faculty also varied, depending on the type of library. Librarians reported a wide range of software employed in the development of these databases highlighting their creation by librarians with various levels of programming skills. Moreover, additional features included in these projects underscore the potential for librarians to provide added value from this service. Finally, while institutional repositories seemingly present similar content, publication databases differ in their focus on a citation format that offers a solution to items without copyright permission for full-text accessibility.  相似文献

Journal coverage is one factor that affects the retrieval of relevant information from bibliographic databases. The aims of this study were to investigate the coverage of databases for psychiatry journals, and to assess the overlap between databases. Psychiatry journals were identified using Ulrich’s International Periodicals Directory and then analysed to see which bibliographic databases indexed the most journals. A total of 213 abstracting and indexing services were listed as indexing at least one of the 977 psychiatry journals identified. The four most frequently cited databases (PsycLIT, EMBASE, BIOSIS and MEDLINE) indexed 506 (52%) of the psychiatry journals. Of these 506 journals, PsycLIT indexed 367 (73%), EMBASE 337 (67%), BIOSIS 243 (48%) and MEDLINE 236 (47%). Combining the databases with the highest yields (PsycLIT and EMBASE) increased the number of journals indexed to 461 (91%). The four databases combined accounted for 90% of all psychiatry journals found to be indexed by at least one abstracting and indexing service. More than 400 journals were not indexed at all. Variations in the overlap between PsycLIT, EMBASE, BIOSIS and MEDLINE, and the high proportion (35%) of journals indexed in only one of these four databases emphasize the importance of searching more than one or even two databases to ensure optimal coverage of the literature.  相似文献
