Background: Measures of the effectiveness of databases have traditionally focused on recall, precision, with some debate on how relevance can be assessed, and by whom. New measures of database performance are required when users are familiar with search engines, and expect full text availability. Objectives: This research ascertained which of four bibliographic databases (bni, cinahl, medline and embase ) could be considered most useful to nursing and midwifery students searching for information for an undergraduate dissertation. Methods: Searches on title were performed for dissertation topics supplied by nursing students (n = 9), who made the relevance judgements. Measures of recall and precision were combined with additional factors to provide measures of effectiveness, while efficiency combined measures of novelty and originality and accessibility combined measures for availability and retrievability, based on obtainability. Results: There were significant differences among the databases in precision, originality and availability, but other differences were not significant (Friedman test). Odds ratio tests indicated that bni , followed by cinahl were the most effective, cinahl the most efficient, and bni the most accessible. Conclusions: The methodology could help library services in purchase decisions as the measure for accessibility, and odds ratio testing helped to differentiate database performance. 相似文献

Objective
The choice of bibliographic database during the systematic review search process has been an ongoing conversation among information specialists. With newer information sources, such as Google Scholar and clinical trials registries, we were interested in which databases were utilized by information specialists and systematic review researchers.Method
We retrieved 144 systematic reviews and meta-analyses from 4 clinical endocrinology journals and extracted all information sources used during the search processes.Results
Findings indicate that traditional bibliographic databases are most often used, followed by regional databases, clinical trials registries, and gray literature databases.Conclusions
This study informs information specialists about additional resources that may be considered during the search process. 相似文献3.

Large scale statewide library cooperation using information technology and wide area networks dates back to the early 1980s with efforts such as the Florida Center for Library Automation and, more recently, the LOUIS Project in Louisiana (see JAL January 1994) and OhioLink (see JAL September 1995). Early efforts were usually focused on the implementation of library information management systems and the provision of shared access to locally held collections, and they often still are. In the 1990s, though, we are witnessing a shift in statewide cooperative use of networks to provide principally access to bibliographic and full-text resources not held locally and usually provided by commercial vendors for use by libraries. As the case studies in this column illustrate the development of funding sources, the technical implementations and support, and the management organization differ from state to state. They reflect, though, the incremental shift in the information landscape towards “electronic libraries”. I choose the word incremental intentionally to reflect that this change has not (at least so far) been anywhere near as rapid or revolutionary as many expected. Nevertheless, what has happened in about 15 years is quite dramatic. It portends a different kind of academic library.—CBL, University of Maryland, College Park. 相似文献

Access to health care machine-readable data files (MRDF) is becoming increasingly important to students and researchers in the health care field who use the data in secondary analysis. Health sciences libraries must play a role in providing such access, and this role should consist primarily in providing users with information about the identity and contents of available MRDF and about how they may be obtained. Libraries should therefore collect extensive materials containing information about the MRDF that may be of interest to their users. Many such materials are available in print, and their quality may be expected to improve as newly developed methods and procedures for constructing bibliographic citations, abstracts, and catalog entries for MRDF are put into practice. Also, it is now feasible to incorporate data file abstracts into existing online bibliographic databases. 相似文献

Pharmaceutical companies often maintain a bibliographic database of published articles on their products. Although such databases share the common purpose of providing the company with a centralized source of published information, the databases themselves vary in scope, uses, and technologies. In order to explore the current status of these databases, a survey was conducted in early 1995. This article provides an overview of pharmaceutical product literature databases and the results from that survey. 相似文献

ABSTRACT Government publications contain a wealth of information. In an effort to increase the usage of these important publications, the staff at Bierce Library, University of Akron, use the following strategies to integrate and advertise government publications into the library activities and the community: (1) cataloging the publications so they appear on the local online catalog as well as the statewide catalog, (2) integrating them into the bibliographic instruction program, (3) listing them in pathfinders as sources on various topics, (4) making them a focus of “hot topics” such as health care reform, (5) presenting and promoting special workshops on specialized government databases such as the National Trade Data Bank and GPO Access (using the flyer approach), (6) visiting your Congressional Representative's Office to increase awareness of the information available in Depository Libraries to his/her constituents, (7) discussing these avenues at state groups, (8) including these methods in conferences, and (9) joining forces with other Documents Librarians in the area to create a depository brochure announcing hours, services, and highlights of each depository collection, and making this information available on a web page. The above strategies are generic enough that libraries can easily implement them into their programs. The effect of these strategies is measured by an increased use of government publications. This can be monitored with circulation statistics and use of electronic products. The results are inconclusive if only circulation statistics are used. 相似文献

The availability of web search engines offers opportunities in addition to those provided by bibliographic databases for identifying academic literature, but their usefulness for retrieving research is uncertain. A rigorous literature search was undertaken to investigate whether web search engines might replace bibliographic databases, using empirical research in health and social care as a case study. Eight databases and five web search engines were searched between 20 July and 6 August 2015. Sixteen unique studies which compared at least one database with at least one web search engine were examined, as well as drawing lessons from the authors’ own search process. Web search engines were limited in that the searcher cannot be certain that the principles of Boolean logic apply and they were more limited than bibliographic databases in their functions, such as exporting abstracts. Recommendations are made for improving the rigour and quality of reporting studies of academic literature searching. 相似文献

The National Library of Medicine (NLM) has an extensive collection of environmental health information, including bibliographic and technical data on hazardous chemical substances, in its TOXNET databases. TOXNET also provides access to the United States Environment Protection Agency (EPA)'s Toxics Release Inventory (TRI) data, which covers release of specific chemicals via air, water, and land, and by underground injection, as reported by industrial facilities around the United States. NLM has developed a Web-based geographic information system (GIS), TOXMAP

An exploratory study to investigate perceived differences between searching full-text databases and bibliographic databases was undertaken. BRS's full-text database, Comprehensive Core Medical Library (CCML), and BRS's current MEDLINE file (MESH) were compared. Identical literature search topics were run in the two databases and the results evaluated regarding currency of search results, success in answering specific questions, uniqueness of information retrieved, and relevancy of retrieval. Additionally, connect time and costs were noted to aid in determining the feasibility of offering full-text database searching as a service for which the authors' institution would charge. 相似文献

Objective: The paper provides an overview of a strategy to increase utilization of online bibliographic databases by public health workers.Methods: A web-based survey of professional staff in the Montana Department of Public Health and Human Services was conducted to assess their use of and interest in training in online bibliographic databases. Based on the findings from the assessment, the department, in collaboration with the state university, provided brief ninety-minute training sessions for interested staff on the use of PubMed.Results: Seventy of 115 (61%) of staff completed the survey. Only 39% of staff reported using an online bibliographic database to conduct a literature search in the past year, and only 10% (n=7) reported having ever received any training in their use. Perceived proficiency with the use of PubMed was higher upon completion of the brief training. The majority of training participants (n=27) indicated that they were very likely to use PubMed in the next year to search the literature.Conclusions: A collaboratively designed training can increase public health workers'' proficiency in and intentions of using online bibliographic databases.
Highlights
- A web-based assessment of Montana public health workers identified a lack of training in and use of online bibliographic databases and an interest in receiving training in their use.
- Brief training in the use of online bibliographic databases increased state public health workers'' self-assessed proficiency in and intentions of using these resources.
Implications
- Low-cost strategies, such as inexpensive web-survey tools, to assess staff needs and brief training sessions for public health workers were effective in increasing public health workers'' self-assessed proficiency in using online bibliographic databases.
- Collaboration between state health departments and universities to design and provide relevant training in the use of online bibliographic databases is an effective approach to addressing public health workers'' skills in using these resources.

The availability of U.S. Government Printing Office bibliographic tapes for copy cataloging or for loading directly into online catalogs may have lulled documents librarians into believing that the problem of bibliographic control for documents collections has been solved. Others may believe that with the move to an electronic distribution system for United States government information, creating and loading bibliographic records for government publications into local library catalogs is becoming an anachronism. This article discusses the functions of cataloging in light of continuing needs and current developments in access to government information. Recommendations are made for ways that the library community, providers of government information, and automation specialists can work together to reexamine bibliographic standards, expand tape loading to non-U.S. depository documents collections, link useful bibliographic databases with library catalogs, and use cataloging of Internet resources to show relationships between physical collections and remotely accessible government information. 相似文献

Romani is a language of northern Indic origin spoken natively by an estimated 2.5 million people, primarily in Eurasia but also in North America. The history of publication patterns in Romani has not been well documented. Extracting data about this history based on available information in large bibliographic databases such as OCLC WorldCat has been hampered by unfortunate misapplication of certain language codes, making it all but impossible to filter search results efficiently using Romani language as a parameter. The author discusses how he was able to correct much of this inaccurate data in OCLC WorldCat. 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

Electronic information resources, such as CD-ROM bibliographic databases, are transforming significantly the way academic researchers find information and the way in which librarians assist academic researchers. CD-ROM and other electronic information resources in academic libraries bring new demands from end-users for services from librarians. In order to meet these new demands for services, academic librarians as information providers must work more closely in an active partnership with researchers and producers of electronic databases. 相似文献

This paper describes the goals, tasks, and main areas of bibliographic control over documents that enter the databases of the Institute of Scientific Information on Social Sciences (INION). It analyzes the features of how bibliographic records of publications on social sciences and humanities (scientific, abstract-analytical, information, scientific-methodical, reference and bibliographic records) are formed. The functions of the software technological complex for automated analysis of the names of persons who are responsible for various types of publications are disclosed. The paper considers the potential of modern software and technological tools for bibliographic analysis and control of bibliographic records, references and citations, including bibliographic managers, scientific work organizers, knowledge managers, and personal information managers. 相似文献

This study seeks to explore institutional repository, social networking, and bibliographic databases of scholarly communication in Nigeria. Six institutional repositories (IR) were selected and five leading authors had their works manually crosschecked in two citation indexes and self-archived in social networking sites. The results reveal that faculty members have embraced self-archive on academic social network platforms, while their records in the IR do not reflect this. The study recommends Universities' management to implore academics to self-archive their publications into their IR, while the libraries too could search bibliographic databases and social network sites to update their respective IR platforms. 相似文献

While machine-readable literary texts have been around for about 40 years, it is only recently that librarians have actively considered acquiring them. Selection has been impaired in large part by problems of bibliographic control and product evaluation. Although costs of machine-readable datafiles are usually higher than are those of the print equivalent, the datafiles provide significant improvements for researchers undertaking stylistic, morphological, semantic, and computational analyses. Service issues associated with software and hardware must be addressed before a particular item is acquired. Storage and preservation needs are also different from those for print media, and may require assistance from departments outside the library, such as computer centers. Literary scholars have developed their own networks to provide information on and access to machine-readable datafiles. Librarians need to be involved in networks and discussions not only to address scholars' concerns, but also to play a role in the future development of such files. 相似文献
