This study was designed to make a comparative evaluation of the performance of MEDLINE in covering serial literature. Forensic medicine was chosen because it is an interdisciplinary subject area that would test MEDLARS at the periphery of the system. The evaluation of database coverage was based upon articles included in the bibliographies of scholars in the field of forensic medicine. This method was considered appropriate for characterizing work used by researchers in this field. The results of comparing MEDLINE to other databases evoked some concerns about the selective indexing policy of MEDLINE in serving the interests of those working in forensic medicine. 相似文献

The mini MEDLINE SYSTEM, a user-friendly search system developed in 1981 at the Georgetown University Medical Center, has been operational since 1982. The system is designed to meet the immediate educational and clinical information needs of students, residents, and faculty. This article focuses on system planning and design, database creation through "downloading," hardware adaptation, and system use. The database is a subset of the NLM's MEDLINE file; it includes over 180,000 citations to articles indexed in over 160 journals from 1982 to the present. With only a few keystrokes in a two-step process it allows users to conduct bibliographic searches. The system is being replicated at eight other medical libraries. 相似文献

The MELVYL MEDLINE project resulted in the addition of a full five-year subset of MEDLINE to the University of California's (UC) MELVYL online union catalog. As one of the nation's largest MEDLINE end-user searching systems, MELVYL MEDLINE provides online bibliographic access to the biomedical journal literature for all UC personnel at over seventy library sites or by remote access. This paper summarizes the project's accomplishments, reports MELVYL MEDLINE use and its impact on library services, and provides insights for other end-user search systems. The project serves as a model for adding databases to the MELVYL catalog and demonstrates the potential for use by other disciplines of a specialized database when readily accessible. Evaluation results report high user satisfaction and high usage. However, many advanced searching features of the interface are little used by searchers. Effects on library services include marked increases in reference transactions and interlibrary loans, with significant declines in mediated search services. Future MELVYL MEDLINE enhancements include matching search retrievals to journal locations, linkage to an online document delivery system, and consideration of building a superset of databases by combining MELVYL MEDLINE with citations from another database in the MELVYL catalog. 相似文献

This study compares six databases which contain information on applied and clinical human nutrition: AGRICOLA, BIOSIS, CAB ABSTRACTS, EMBASE, MEDLINE, and SCI-SEARCH. Five research questions were searched, and the results were compared to identify the database of first choice and to determine the degree of overlap among the databases. Results indicate that for most of the human nutrition questions searched, MEDLINE was the most productive database. However, MEDLINE alone only uncovered 24% to 69% of the citations available. A combination of MEDLINE and at least one other database is recommended. The results of this study suggest that for most human nutrition questions, AGRICOLA is the best file to complement MEDLINE. 相似文献

The implementation of MELVYL MEDLINE, a successful online end-user system in the University of California (UC) health sciences libraries greatly enhanced the capabilities of reference desk service by providing immediate access to current medical literature from the MEDLINE database. With these enhancements, the extent of the impact on the delivery of reference service was not anticipated. Concurrent with providing traditional reference service requests, there was a constant need for individualized end-user instruction by MELVYL MEDLINE users, and continual maintenance of workstation equipment and supplies. This paper describes the experiences at the UC Irvine (UCI) Biomedical Library and compares these experiences with other UC health sciences libraries. The purpose of this paper is to discuss some of the issues which must be considered when planning for the implementation of an end-user system within the reference service function. 相似文献

MEDTUTOR is an interactive, microcomputer-based training package designed to teach medical and health professionals, as well as librarians and information specialists, how to use MEDLINE effectively. The objective of MEDTUTOR is to provide a comprehensive package for teaching the various commands and search techniques required for utilizing the MEDLINE database through the MEDLARS system. MEDTUTOR's menu-driven design allows novice users to learn about the content and use of MEDLINE, such as author searching, text word searching, MeSH indexing, etc., at their own pace and with considerable program feedback. In addition, MEDTUTOR provides the skilled searcher with a way to reinforce or recall previously-learned search techniques without incurring online charges. MEDTUTOR may be used in place of formal training, as a precursor to or as a refresher following formal training, or for review of a particular concept. It provides inexpensive and easily accessible instruction for searching MEDLINE. 相似文献

Objective:We aimed to determine overlaps and optimal combination of multiple database retrieval and citation tracking for evidence synthesis, based on a previously conducted scoping review on facilitators and barriers to implementing nurse-led interventions in dementia care.Methods:In our 2019 scoping review, we performed a comprehensive literature search in eight databases (CENTRAL, CINAHL, Embase, Emcare, MEDLINE, Ovid Nursing Database, PsycINFO, and Web of Science Core Collection) and used citation tracking. We retrospectively analyzed the coverage and overlap of 10,527 retrieved studies published between 2015 and 2019. To analyze database overlap, we used cross tables and multiple correspondence analysis (MCA).Results:Of the retrieved studies, 6,944 were duplicates and 3,583 were unique references. Using our search strategies, considerable overlaps can be found in some databases, such as between MEDLINE and Web of Science Core Collection or between CINAHL, Emcare, and PsycINFO. Searching MEDLINE, CINAHL, and Web of Science Core Collection and using citation tracking were necessary to retrieve all included studies of our scoping review.Conclusions:Our results can contribute to enhancing future search practice related to database selection in dementia care research. However, due to limited generalizability, researchers and librarians should carefully choose databases based on the research question. More research on optimal database retrieval in dementia care research is required for the development of methodological standards. 相似文献

The emergence of CD-ROM (compact disc/read-only memory) versions of the MEDLINE database requires experienced MEDLINE searchers to examine assumptions about searching MEDLINE, since some expectations may not be fulfilled by this new technology. When applied to a particular CD-ROM MEDLINE product, the evaluation procedure involves testing assumptions concerning database contents; mechanics of searching; display, print, and download capabilities; and user-friendly features. The extent to which a CD-ROM product preserves and exploits important MEDLINE strengths should be assessed, e.g., the MeSH controlled vocabulary, the designation of major and minor MeSH emphasis, and the use of subheadings. Search software characteristics that affect ease of searching and quality of results also need to be examined, e.g., the ability to truncate search terms and the order of precedence in which Boolean operators are evaluated. A checklist to assist in the evaluation process is presented, including search examples for use in testing search functions. 相似文献

This article provides a brief history of the development of the MEDLINE database and its huge impact within the UK, from its inception to the present time. The origins of MEDLINE can be traced back to a collection of books in the US Surgeon General's Office during the American Civil War and John Shaw Billings' decision, during 1867, to make this Library as complete as possible. From these beginnings, Index Medicus was developed in the early years of the 20th century, and electronic versions of the database began with the computerized on-demand search service MEDLARS in 1964 and then via CD-ROM and Internet Grateful Med to the web-based and free-to-all service, PubMed, in 1997. The response to PubMed was immediate and startling with usage increasing from 7 million searches per annum in 1996 to 400 million searches per annum in 2001 and the service continues to improve. MEDLINE providers are now offering mapping of natural language queries to the sophisticated indexing vocabulary (Medical Subject Headings, MeSH) and the provision of specific filters for different types of publication to improve searching efficiency, as well as links to full-text versions of the papers where available. The next steps are likely to involve an increased blurring of database and full-text boundaries, incorporating seamless access to the best available evidence within MEDLINE and a wide range of other information resources within a single search and to an increasing amount of full-text via various open-archive initiatives. As ever, the US National Library of Medicine is in the vanguard of research and further applications of its MEDLINE database for users within the UK will be awaited with great interest. 相似文献

The MEDLINE database available on BRS provides searchers with flexible capabilities for efficient searching. Several new and unique features are highlighted and illustrated. The special sort and merge features are described for enhancing printouts. Several non-traditional uses of the MEDLINE database are suggested: interlibrary loan verification, table-of-contents service, and cross-file searching of companion BRS produced PRE-MED and PRE-PSYCH databases. 相似文献

The Southeast Florida AIDS Information Network: a community outreach, specialized information system
In the years ahead, end-user instruction will expand from the current models of curriculum- and institution-based programs for teaching MEDLINE to include outreach programs to unaffiliated users for teaching specialized database searching. The Southeast Florida AIDS Information Network (SEFAIN), a community-based information system targeting health care providers in a tri-county area, is an example of this new model. The components of SEFAIN and the results of the outreach and educational programs are presented. The advantages of these programs to both providers and librarians are highlighted. Comparisons are drawn between end users who take specialized information courses and those who take MEDLINE courses or no courses. These data will assist librarians in the justification and development of specialized information systems. 相似文献

This study compared features and determined which of four end-user systems (PaperChase, GRATEFUL MED, Med-Base, or Compact Cambridge: MEDLINE) would best serve the Medical Sciences and Optometry Libraries of Indiana University in providing biomedical information to faculty and graduate students through MEDLINE. Cost, ease of use, retrieval, training needs, equipment requirements, and adequacy of documentation were examined. The study consisted of a comparison of the features of each system based on available documentation; a controlled search performed by the investigators on each system and on regular NLM MEDLINE; and a user study based on observations, questionnaires, and interviews with eleven library patrons who performed the same search of their choice on each of the four systems. 相似文献

The development of services provided by the National Library of Medicine (NLM), which dates back to 1836, is described. MEDLINE, a database of 10-plus million references and abstracts to the world's biomedical literature, was put on the World Wide Web for free searching in 1997 as a system called PubMed, whose use has grown to over 250 million searches per year. PubMed features a variety of links between MEDLINE references and related information – full-text journal articles, DNA sequence data, medical knowledge bases, etc. – at websites within and outside NLM. PubMed is a major component of a larger NLM system, Entrez, which integrates access to a number of genome-related databases with linking features similar to those of PubMed. The newest linked service, which became a reality in February 2000, is PubMed Central, the National Institutes of Health's free repository for primary research reports in all the life sciences. 相似文献

The Internet has created new opportunities for librarians to present literature search results to clinicians. In order to take full advantage of these opportunities, libraries need to create locally maintained bibliographic databases. A simple method of creating a local bibliographic database and publishing it on the Web is described. The method uses off-the-shelf software and requires minimal programming. A hedge search strategy for outcome studies of clinical process interventions is created, and Ovid is used to search MEDLINE. The search results are saved and imported into EndNote libraries. The citations are modified, exported to a Microsoft Access database, and published on the Web. Clinicians can use a Web browser to search the database. The bibliographic database contains 13,803 MEDLINE citations of outcome studies. Most searches take between four and ten seconds and retrieve between ten and 100 citations. The entire cost of the software is under $900. Locally maintained bibliographic databases can be created easily and inexpensively. They significantly extend the evidence-based health care services that libraries can offer to clinicians. 相似文献
