Although database access has been available via search intermediaries for some time, online services are now encouraging end users to search databases directly. In response to this trend, librarians are taking on new end-user training and support roles. But is this training effort worthwhile? The relationship between online training received and the level of implementation of end-user searching is discussed using survey data from 124 Canadian health professionals (response rate 83%). There was a positive relationship between the number of training events reported and implementation level. Several different kinds of training, in addition to formal courses, were reported by end users. The use of Medical Subject Headings (MeSH) was related to more positive perceptions of online searching which, in turn, predicted higher implementation levels. Variability in the implementation levels of the respondents suggests that end users are a diverse group with different information needs and degrees of searching expertise. Various types of both formal and informal training will continue to be required by end users.  相似文献

The increasing availability of computerized information sources and networking capabilities, along with the proliferation of microcomputers in faculty homes and offices, has led to increased demands for direct access to databases. The librarian's role as online search intermediary appears to be changing from performing searches directly to aiding users in doing their own searching. The Research Libraries Information Network (RLIN), one of the major cataloging utilities, offers a wealth of bibliographic information in both its online union catalog, and its many specialized files. The University at Albany Libraries participated in a pilot project involving faculty end-user access to RLIN. This paper reports on the Libraries' experience with the pilot project and the continuing end-user access program for faculty. Despite some reservations about the relative user-friendliness of the RLIN search system, the author enthusiastcally endorses the use of RLIN as an end-user database.  相似文献

Investigation of end-user searching at the New York Hospital-Cornell University Medical Center (NYH-CUMC) revealed that 8% of the physicians surveyed were end users, 63% were interested in learning to search, and 29% were not interested. When training sessions were offered at the Burke Rehabilitation Center, an affiliated institution, 50% of the medical staff attended at least one class, but only 7% of the total staff became frequent searchers. Analysis of the precision and recall ratios of searches conducted by five end users at HYH-CUMC indicated that the best results were obtained by end users who had been taught to search by experienced librarian-searchers. The quality of end user searches did not appear to be affected by the "friendliness" of the systems used, the frequency of searching habits, or the length of time that an end user had been searching.  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

Through casual observations, formal consultations, and educational sessions, the authors have identified various indexing features of the National Library of Medicine's Medical Subject Headings (MeSH) that pose challenges to end users while attempting to obtain relevant retrieval when searching MEDLINE. These problematic features include the use of Explodes, Tree structures, subheadings, Text Word vs. subject heading searching, and central concept searching. End-user search software is becoming more sophisticated with an increasing number of choices offered for search strategy formulation. Methods of instruction to orient the end user to these systems will also have to become more detailed. A review of the literature, that discusses end-user problems with using MEDLINE and MeSH, is included.  相似文献

Through casual observations, formal consultations, and educational sessions, the authors have identified various indexing features of the National Library of Medicine's Medical Subject Headings (MeSH) that pose challenges to end users while attempting to obtain relevant retrieval when searching MEDUNE. These problematic features include the use of Explodes, Tree structures, subheadings, Text Word vs. subject heading searching, and central concept searching. End-user search software is becoming more sophisticated with an increasing number of choices offered for search strategy fomalation. Methods of instruction to orient the end user to these systems will also have to become more detailed. A review of the literature, that discusses end-user problems with using MEDLINE and MeSH, is included.  相似文献

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

OBJECTIVE: To evaluate the adequacy of the MEDLINE instruction routinely given to all entering medical students at the University of Miami School of Medicine and the ability of students to search effectively for and retrieve evidence-based information for clinical decision making by the end of their third-year. METHODOLOGY: The authors developed and implemented a strategy for evaluating the search strategies and articles selected by third-year students, who participated in the Objective Structured Clinical Examination (OSCE) in June 1996, 1997, and 1998, and reviewed the literature on evidence-based medicine and evaluation of medical student searches. RESULTS: A mean of 5% of the students' search strategies and a mean of 26% of articles selected were ranked "excellent" or "good"; a mean of 26% of search strategies were ranked "fair" and a mean of 69% were ranked "poor"; and a mean of 22% of articles selected were ranked "fair" and a mean of 52% were ranked "poor" based on the strategy developed to evaluate student searches. CONCLUSIONS: Evaluating medical student searches for evidence-based information is an effective way of evaluating students' searching proficiency, and, in turn, the adequacy of the instruction they receive. Based on the results of the OSCE test, the school of medicine expanded the library's educational role and the library implemented major changes in the training program. Information on evidence-based medicine is now incorporated into the MEDLINE instruction. Library faculty evaluate the required searches performed by students for evidence-based information during their first and second years; 30% of students are identified for follow-up, individualized instruction based on the evaluation; and a new case-based curriculum has been proposed with a fourteen-week problem-based learning (PBL) block. These developments are timely in light of the evidence-based competencies recently published by the Association of American Medical Colleges.  相似文献

Background: Most NHS library services routinely offer both mediated searches and information skills training sessions to their users. We analyse the impact of these two services on the amount of literature searching demonstrated by users of hospital‐ based library services in the north‐west of England. Methods: Data for (1) mediated literature searches, (2) number of library users attending information skills training sessions, (3) amount of library staff time devoted to information skills training, and (4) number of Athens‐authenticated log‐ins to databases were obtained from statistical returns for 2007, and analysed for significant correlations. Results: There was evidence of quite strong correlations between the two measures of training activity and the number of mediated literature searches performed by library staff. There was weaker evidence of correlation between training activity and total literature searching activity. Discussion: Attending training sessions may make some library users aware of the difficulty of complex literature searches and actually reduce their confidence to perform their own complex searches independently. The relationships between information skills training, mediated literature searches, and independent literature searching activity remain complex.  相似文献

The argument that mediated online ready reference searching is an indispensable service is presented. The proliferation of Internet resources, including electronic journals, online catalogs, and other resources creates new user expectations and demands on reference service points. While end-user searching makes sense when a common interface for a multitude of diverse databases is provided, the contemporary version of remote access challenges searchers to tackle nearly every type of vendor product available as well as several homegrown varieties. Until "intelligent systems" can span the diversity of available online systems, librarians may once again find themselves in the role of search mediator that was common when online databases were first introduced while the task of keeping reference librarians apprised of developing electronic resources is formidable, end-user instruction is even more so. Because the diversity of online systems makes it impractical to know each system in very much detail, reference librarians will need to concentrate on developing a better conceptual framework.  相似文献

Information overload interferes with our abilities to use information effectively. It represents a challenge in searching print as well as online collections. Academic librarians have developed strategies to help their patrons reduce the effects of information overload. This article provides best practices employed by academic librarians to reduce their users’ information overload. Five themes emerged in a review of the literature: information presentation, library instruction, user strategies, librarian roles, and software technologies. Information literacy instruction remains particularly important in combating information overload since the promotion of users’ research skills facilitates their search competencies. Research on information problem solving that focuses on metacognitive strategies may help decrease information overload among users searching digital libraries.  相似文献

This study analyzed observations and interviews of 31 participants, who were divided into six age groups, to understand the influence of end-user goals and experience on Internet search approaches. Users who lacked experience approached the Internet similarly no matter what the age group. Children and older adults were more likely to lack online search experience than other users. In addition, children and older adults were more homogeneous than other users in that they had a narrow range of situational goals, whereas users in other groups had a wide range of situational goals. The study has implications for user services and research in end-user searching. An understanding of the influence of age, experience, and goals on Internet search patterns might guide how, how much, and in what format information should be presented in the future. Knowledge gained from this study can also form the basis of hypotheses for larger studies.  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

Research informationists at a comprehensive cancer center sought to evaluate the impact and value of mediated literature searches in support of their users’ work activities. An assessment tool was identified in the literature and modified by the investigators to solicit feedback from library users and identify the major reason(s) why scientists and health care professionals request literature searches, how they use the resulting information, and the impact that the results may or may not have on their research or patient care/decision-making activities. Survey results were qualitatively analyzed, and future avenues of outreach and promotion of mediated literature search services were identified.  相似文献

Summary

This study examines the search tactics used by Web users to start their searches and deal with search problems such as too many postings and no relevant postings. Four search topics were developed to allow for comparison of search tactics used in four types of searches. The tactics analyzed include search statements, number of search statements, starting points, and tactics to solve the two search problems mentioned above. Search statements were searched in Alta Vista to determine their success and their nature was analyzed. With regard to the tactics used to address search problems, t-tests and chi-square tests found no difference between searches for texts and searches for graphic information, and between known-item searches and subject searches. Some of Web users' search tactics were similar to those for online searching or online catalog searches, but several tactics were unique to Web searching.  相似文献

There is a current trend to make museum collections widely accessible by digitising cultural heritage collections for the Internet. The present study takes a user perspective and explores the characteristics of online museum visitors' web search behaviour. A combination of quantitative and qualitative methods was deployed in a case study at a National Museum of Military History. Quantitatively, data from a web questionnaire survey and a user study of interactive searching behaviour were collected and analysed. Qualitatively, observation protocols were coded and analysed based on inductive content analysis. It was found that metadata elements on factual object related information, provenience, and historic context was indicated to be relevant by the majority of the respondents, characterising the group of special interest museum visitors as information hungry. Further, four main characteristics of online museum visitors' searching behaviour were identified: (a) searching behaviour has a strong visual aspect, (b) topical searching is predominantly exploratory, (c) users apply broad known item searches, and (d) meaning making is central to the search process.  相似文献
