The University of Oklahoma Health Sciences Center (OUHSC) Library conducted a two-year program, funded by the National Library of Medicine (NLM), to teach Oklahoma's nonurban health professionals to perform searches of NLM's MEDLINE files using microcomputers. The training program included lectures, online demonstrations, and hands-on practice time. The initial target audience of non-urban physicians was later broadended to include other health professionals. Data collected on the 334 seminar participants included professions and specialties, previous microcomputer usage, and the size of their hospitals. On-site evaluation indicated a high degree of satisfaction with the trainers' communication skills, preparation, information imparted, and the visual aids used. The results of a follow-up survey to determine how many trainees subsequently obtained NLM codes, the amount of searching done, and the problems experienced await analysis. 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

The Alfred Taubman Medical Library at the University of Michigan has offered instruction in online literature searching to third-year pharmacy students as a component of the course "Drug Information and Scientific Literature Evaluation" since 1983. In the spring of 1989, a follow-up study was conducted to assess the impact of instruction on four classes of graduates. Of a pool of 151 graduates, 90 (60%) responded to a mailed questionnaire on their use of information and computerized literature searching. The respondents were divided into four subgroups: end-user searchers, users of intermediaries, end users who used intermediaries, and those who did not use computerized literature search systems. Seventy-two percent of the respondents used some type of computerized literature searching, and 42% performed their own searches. The four subgroups differed in general computer use, familiarity with MEDLINE search terminology, information use, reasons for using or not using literature searching, and characteristics of searches (i.e., type, time frame, amount, and frequency). Training in end-user search systems appears to have had an impact on the continued use of computerized literature searching several years after the formal educational program. 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 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

Searching for patterns in the MeSH vocabulary 总被引：1，自引：0，他引：1
NLM revises its MeSH vocabulary annually to reflect changes in biomedical literature and the health sciences community. This study tested two hypotheses about NLM's MeSH vocabulary. The first is that new terms are added to MeSH when their broader terms have an increased number of postings. One examination compared the number of postings for the broader terms of new and existing terms in the current MEDLINE file; the other compared them over time. No significant statistical difference was found in either case. A second hypothesis--that there is a relationship between the patterns of MEDLINE indexing and searching and the organization of the MeSH tree structure--was tested by comparing the distribution of searched terms in the MeSH trees with the distribution of all terms. It was found that certain trees are searched more often than could be predicted by the overall term distribution, while others are searched less frequently than expected. In summary, (1) new terms cannot be predicted by the increase in postings of existing terms, and (2) searchers' and indexers' use of the terms' tree structure does not correlate with the terms' distribution in the MeSH trees. 相似文献

Locating notes about MeSH subheadings can be one of the most difficult aspects of MEDLINE searching. When used with Medical Subject Headings (MeSH), subheadings serve to limit or define the focus of a heading. National Library of Medicine (NLM) indexers, staff members who enter the MeSH indexing into the database, use subheadings freely. They do follow indexing conventions and savy searchers need to be aware of how to obtain basic subheading information to assist in search formulation. There are a number of methods which may be used in order to view subheading use notes. This column will provide an overview of some alternatives to locating such information. 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

Scott Memorial Library (SML) at Thomas Jefferson University has installed the Library Information System (LIS) developed by Georgetown University Medical Center Library. One component of the system is miniMEDLINE, a system for searching an inhouse database derived from NLM MEDLINE tapes. This paper describes the process involved in determining which journals should be included in SML's miniMEDLINE file; the number of titles and years covered; the balance between research and clinical titles; the representation of allied health fields; and the level of faculty involvement. 相似文献

A survey to determine attitudes toward end-user searching was made at Loyola University's Medical Center Library using MEDIS, an online full-text and bibliographic medical retrieval system. One hundred forty-one completed questionnaires were analyzed for this report. Information was collected on user familiarity with computers, end-user training, system use, mechanics of searching, and attitudes toward future use. Computer familiarity was highest among the faculty users. Ninety percent of the respondents saw librarians as a crucial agent in training and in providing end-user assistance. Respondents identified five major reasons for using the system: helpfulness, convenience, time savings, rapid feedback, and presentation of needed information. Searching the MEDLINE database rather than the full-text database was the search method of choice. Continued use of both mediated and end-user searching was intended by most of the respondents. Survey results support a perceived need for end-user searching and confirmed recommendations of the Association of American Medical Colleges on medical information science skills. 相似文献

A questionnaire was sent to all medical school libraries listed in the Annual Statistics of Medical School Libraries in the United States and Canada (1983-1984) asking librarians to describe their end-user programs. Of the 113 responding libraries, 78 had an end-user program. All provided some kind of formal instruction, 39 made equipment available to end users, and 22 provided and administered passwords. The reasons most cited for starting a program were staff interest and patron requests. The two most frequently taught systems were NLM/MEDLINE and BRS/Colleague. In general, respondents felt positive about the programs and planned to continue them. The most frequently mentioned problem was need for more equipment. 相似文献

The authors ask whether full-text versions of medical journals are available for searching sooner than their biblographic counterparts. The journals in question are those found in the Comprehensive Core Medical Library (CCML) from BRS Information Technologies and in Mead Data Central's MEDIS Current Journal Files. All journals in these two files are full-text, and neither file contains any indexing features. Update schedules for the full-text version of the MEDLINE journals in each of these files were compared with the most recent issue available in the National Library of Medicine's (NLM) MEDLINE on five different dates. The data revealed substantial fluctuation in comparative currency for MEDIS/MEDLINE over the period of the test. On the date of the last snapshot, June 8, 1990, MEDLINE and MEDIS were offering the same currency for 43% of the journals, and MEDIS was providing first access to 29% of the titles. The CCML/MEDLINE comparison showed less variation. In the last snapshot MEDLINE and CCML were providing access to the same issue for 36% of the journals, and CCML was offering first access to 14%. Prior to publication, this paper was submitted to all three vendors for comment. Significant portions of their responses are quoted. 相似文献

The NLM Gateway is a single Web interface for searching multiple NLM databases. While the majority of the available databases can be accessed directly via their own Web sites, such as PubMed, there are three databases that are unique to the NLM Gateway, including the ever-expanding OLDMEDLINE files. Thus, the Gateway is a necessary tool for librarians and researchers to be familiar with and have handy. 相似文献

The National Library of Medicine has established at the Biomedical Library, UCLA, a remote MEDLARS search station. The agreement between the libraries provided that the Biomedical Library in cooperation with the UCLA Health Sciences Computing Facility would reprogram MEDLARS for the IBM 7094 computer, provide personnel to be trained in machine searching at NLM, and engage in a pilot demonstration of search service to the medical staff of UCLA. This paper describes the place of the search section in the organization of the Biomedical Library and the training of personnel at NLM (the article by Garvis in this issue of the Bulletin relates the problems encountered in making two different computer systems compatible). Search service had not begun when this paper was written; it was scheduled to begin late in 1965. Plans for the future include the enlargement of the UCLA MEDLARS staff and extension of search service to a larger geographical area. 相似文献

A formal study was attempted to assess the utility of the various online database sources for obtaining material in the fields of occupational and environmental health. Five databases were studied comparatively: BIOSIS, ENVIROLINE, EXCERPTA MEDICA, MEDLINE, and TOXLINE. In addition to crossdatabase searching to draw comparisons, a study of the journal coverage of four of these databases was completed. The goal of this effort was to establish some "databases of choice" for searching the literature. 相似文献

MEDLINE (MEDLARS-ON-LINE) is the new on-line, interactive bibliographic searching system which was recently developed by the National Library of Medicine. The system provides users with lists of bibliographical citations and other information from a three-year file of over 1,250 biomedical journals. A survey testing user reactions was conducted at the University of Virginia Medical Library. The results of the survey are based on replies by 246 users who requested one or more MEDLINE searches between September 1972 and March 1973. The findings indicate that over 93% believe that MEDLINE is a substantial improvement over the traditional methods of searching through the printed indexes. These respondents also stated that the results of MEDLINE searches had assisted them in their clinical or research work, or both. Asked whether they would continue to use MEDLINE after the imposition of user charges on July 1, 1973, about 75% said that they would. The remaining 25% expressed some reservations and doubts. The survey gives reason to believe that with the imposition of user charges the use of MEDLINE will decline. 相似文献

The use of MEDLINE at the Calder Memorial Library of the University of Miami School of Medicine has grown so substantially over the past one and one-half years that we felt an evaluation of the service was appropriate. A one-page questionnaire was sent to 350 patrons who had requested MEDLINE searches in 1973. The response validated many of our assumptions about the user group and their reasons for using MEDLINE. Most surprising were the degree of enthusiasm, the willingness to pay out of personal funds, the apparent lack of knowledge about SDILINE, and the small number of critical comments. We expect that the experience gained from this assessment will enable us to make improvements in some aspects of our service, as well as to undertake more subject-specific evaluations at shorter intervals in the future. 相似文献
