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

This article is an exploration of techniques for identifying items in the health related literature using NLM system databases. Examples used are derived from reference desk and interlibrary loan files, but the techniques should be useful to any medical librarian who needs to verify a citation. A knowledge of NLM indexing practices and system commands is assumcd. Because of mace limitations the TOXLINE. TOXBACK74, TOXBACK65,AVLINE files have been omitted, but other bibliographic files and SERLINE are included. Tables designed for at-terminal use are presented. 相似文献

Searching by subject for monographic information online in the medical literature is a challenging task. The NLM database of choice is CATLINE. Other NLM databases of interest are BIOTHICSLINE, CANCERLIT, HEALTH, POPLINE, and TOXLINE. Ten BRS databases are also discussed. Of these, Books in Print, Bookinfo, and OCLC are explored further. The databases are compared as to number of total records and number and percentage of monographs. Three topics were searched on CROSS to compare hits on BBIP, BOOK, and OCLC. The same searches were run on CATLINE. The parameters of time coverage and language were equalized and the resulting citations were compared and analyzed for duplication and uniqueness. With the input of CATLINE tapes into OCLC, OCLC has become the database of choice for searching by subject for medical monographs. 相似文献

Health Services Technology/Assessment Text (HSTAT), an online collection of documents pertaining to clinical practice guidelines, HIV/AIDS treatment information, and health care decision making, was recently introduced by the National Library of Medicine. Access to HSTAT is available through the NLM Full-Text Retrieval System (FTRS), a document search and retrieval system developed by the Information Technology Branch of NLM. Internet FTP, Gopher, and World Wide Web clients may also be used to obtain documents from the HSTAT collection. 相似文献

As part of a U.S government effort to combat AIDS, the National Library of Medicine (NLM) is expanding its information services in this area. In response to the Health Omnibus Program Extension Act of 1988, NLM has expanded its AIDS Bibliography, enhanced its DIRLINE file with AIDS-related organizations, and developed three new online MEDLARS (Medical Literature Retrieval and Analysis System) databases: AIDSLINE, AIDSTRIALS, and AIDSDRUGS. NLM's AIDS-related programs and services are discussed. 相似文献

MEDLINEplus: building and maintaining the National Library of Medicine's consumer health Web service 总被引：1，自引：0，他引：1
MEDLINEplus is a Web-based consumer health information resource, made available by the National Library of Medicine (NLM). MEDLINEplus has been designed to provide consumers with a well-organized, selective Web site facilitating access to reliable full-text health information. In addition to full-text resources, MEDLINEplus directs consumers to dictionaries, organizations, directories, libraries, and clearinghouses for answers to health questions. For each health topic, MEDLINEplus includes a preformulated MEDLINE search created by librarians. The site has been designed to match consumer language to medical terminology. NLM has used advances in database and Web technologies to build and maintain MEDLINEplus, allowing health sciences librarians to contribute remotely to the resource. This article describes the development and implementation of MEDLINEplus, its supporting technology, and plans for future development. 相似文献

The Drug Information Portal is a free Web resource from the National Library of Medicine (NLM) that provides a user-friendly gateway to current information for more than 15,000 drugs. The site guides users to related resources of NLM, the National Institutes of Health (NIH), and other government agencies. Current drug-related information regarding consumer health, clinical trials, AIDS, MeSH pharmacological actions, MEDLINE/PubMed biomedical literature, and physical properties and structure is easily retrieved by searching on a drug name. A varied selection of focused topics in medicine and drugs is also available from displayed subject headings. This column provides background information about the Drug Information Portal, as well as search basics. 相似文献

The latest release of GRATEFUL MED offers medical libraries an opportunity to monitor searching patterns of end users searching the databases of the National Library of Medicine (NLM). A GRATEFUL MED use log records information from each search session. Analysis of the log from a recent beta test program at the Welch Medical Library indicates that most NLM searches occur in the MEDLINE database. Moreover, the study reveals that searchers overlook many user-friendly features of the program. Evaluation of the use log suggests changes for future versions of the program. 相似文献

An increasing number of users are reaching out to their academic library from their mobile devices to search for scholarly content. As a result, the resources offered through the library Web site should be equally accessible on all devices. Database content is a critical library resource, and vendor products must evolve to function effectively on all types of devices. This study examined 197 databases at Adelphi University Libraries to determine if they are universally accessible either through the provision of an app or a mobile-optimized Web site. The study concluded that the majority of vendor platforms are not optimized for viewing across smart devices. These findings indicate that libraries should encourage vendors to offer mobile-optimized databases, and desktop computers may still be necessary for database searching. 相似文献

In March 1985, the National Library of Medicine (NLM) began implementation of DOCLINE, its automated interlibrary loan request routing and referral system. By the end of fiscal year (FY) 1987, over 1,400 biomedical libraries in all seven regions of the Regional Medical Library network were using the system. This report summarizes the findings of an analysis of the interlibrary loan (ILL) requests received in FY 1987, comparing the results with a similar analysis done in FY 1984 to describe any changes in the requests or service which might be attributable to DOCLINE implementation. DOCLINE has had a substantial impact upon ILL loan service at NLM. An increase in the number of ILL requests (35% over FY 1984) can be attributed to the speed and ease with which requests may be routed to NLM through DOCLINE. Requests which cannot be filled by local or regional libraries are automatically routed by the system to NLM as the library of last resort. NLM's fill rate for serial requests has declined, however, from 78% filled in FY 1984 to 67% filled in FY 1987. Some of the decline results from the 11,000 requests that NLM did not fill because the borrowing libraries were not willing to pay the NLM charge for filling the loans. 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

Libraries are constantly challenged to find ways to demonstrate their value to their institutions. Can hosting a National Library of Medicine (NLM) exhibition increase a library's impact? In 2012 the University of Toledo engaged their constituents by hosting and developing programming for the NLM exhibit Harry Potter's World: Renaissance Science, Magic and Medicine. The process is synthesized into five stages: choosing, visioning, finding allies, budgeting, and marketing. Recommended practices for each stage are presented. Measures of impact (attendance, views, tweets, feedback) are discussed. Author concludes that hosting NLM exhibitions can be cost effective ways to advance a library's mission, improve visibility and user's perceptions. 相似文献

ABSTRACTThis article analyzes 37 Orbis Cascade Alliance members' Web sites to determine ease of use across mobile devices. Based on that analysis and a literature review, guidance is provided on how libraries' mobile Web sites may be improved. Web sites were examined to determine ease of locating frequently accessed resources on mobile devices that were identified in the literature: contact information, hours, databases, library accounts, and search boxes. Scalability of Web sites on mobile devices was also evaluated and was found to be non-existent in nearly a quarter of examined libraries. Areas for consideration and improvement are presented across Orbis Cascade Alliance libraries that can easily be applied globally. 相似文献

The National Library of Medicine (NLM) has a broad mission in biomedical information service. There are three major reasons for NLM, as a national institution, having an international program: first, the global nature of disease; second, the international scope of medical literature; and third, the universal goal of better communication. This paper reviews NLM's programs in relation to international medical information exchange: International MEDLARS Centers, collaboration with WHO and PAHO, NLM Special Foreign Currency Program, and development of the NLM collection. 相似文献

The metastrategy for World-Wide Web information retrieval was presented as an integrated approach to end-user searching in clinical medicine, although its application may be made to any search for WWW information. Certain distinctions, such as between anticipated and unanticipated clinical information needs and between WWW catalogs for retrieving Web sites and WWW databases for retrieving Web pages, were made. These distinctions are important in the end-user strategy because they help maximize the productivity of the WWW for clinicians. 相似文献
