Since 1970, Indiana University School of Medicine Library (IUSML) has traditionally been a high volume online searching institution. The library recently implemented an end user searching program which includes MEDLINE on CD-ROM. The effect of CD-ROM on online end user and mediated searching is discussed. Comparative statistics are provided by category of search service. CD-ROM has had a dramatic lowering effect on online end user searching and has had little effect on mediated searching. IUSML's experience with CD-ROM technology has been a positive one. Trained end users have become IUSML's greatest asset.  相似文献

The relationship between the development of mediated online literature searching and the recruitment of medical librarians to fill positions as online searchers was investigated. The history of database searching by medical librarians was outlined and a content analysis of thirty-five years of job advertisements in MLA News from 1961 through 1996 was summarized. Advertisements for online searchers were examined to test the hypothesis that the growth of mediated online searching was reflected in the recruitment of librarians to fill positions as mediated online searchers in medical libraries. The advent of end-user searching was also traced to determine how this trend affected the demand for mediated online searching and job availability of online searchers. Job advertisements were analyzed to determine what skills were in demand as end-user searching replaced mediated online searching as the norm in medical libraries. Finally, the trend away from mediated online searching to support of other library services was placed in the context of new roles for medical librarians.  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

Summary

The transition of academic library reference resources from print to electronic format has been characterised by a growing level of strategic decision making by librarians, as mediated searches were replaced by end-user CD-ROM formats, only to be superseded by online user access. The experience of Australian university libraries, which were early adopters of these changes, is outlined. Particular factors which impacted on this transition in other English-speaking countries (the United Kingdom, United States, Canada, and South Africa) are also described. The formation of purchasing consortia has been crucial in all countries in facilitating this transformation of reference collections.  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

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

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

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

This paper examines end-user, online searching using data from a questionnaire mailed to 150 Canadian health professionals in practice settings. The response rate was 83% (n = 124). The data provide a demographic profile of early adopters of end-user searching in the health care community. Positive correlations with the user's level of implementation of end-user searching were found for the following variables: amount of time spent in research activities, amount of system training received, and use of Medical Subject Headings (MeSH). There was a negative association between the amount of time spent in patient care and implementation level. General practitioners and family physicians had lower implementation levels than physicians in other specialties. Successful implementers were more likely to be computer literate and to place a high value on formal information sources such as books, journals, and libraries. Health professionals using so-called "user-friendly" or menu-based software had lower levels of personal commitment to using online databases, as measured by a combination of continuance of use, willingness to pay personally, type of recommendations made to colleagues, and hardware ownership.  相似文献

The nature of bibliographic instruction in this hospital library continues to evolve. As the library makes easy-to-master, menu-driven tools for online searching available to end users, the demand for this service and the accompanying training increases. The demand for formal sessions covering research techniques is also increasing. Upon request, the library offered an extended research orientation to the housestaff in Obstetrics and Gynecology in May of 1993. An introduction to the use of CD-ROM was included to highlight its usefulness for citation verification, author searches, and for periodic current awareness searches on a particular topic. The UMH Library staff strive to offer the most current and comprehensive facilities and services to their users. These include automated access to the library's book, journal, and audiovisual holdings using the Data Trek system; online bibliographic searching by library staff and end users using CD Plus MEDLINE on CD-ROM and Grateful MED software; participation in clinical rounds to provide research support for clinical care; and several types of bibliographic instruction. In addition to the informal teaching of library research techniques that the library staff offers on a daily basis, the Library at Union Memorial Hospital is pleased to be able to provide a formalized and evolving bibliographic instruction program.  相似文献

Public libraries have added access to online intermediary searching and end-user systems, but have not based the decision to do so on in-depth study of needed skills, impact on staff and projected benefit to patrons. If quality online searching is to be provided, methods of staff selection and development need to be seriously considered. The role of the online searcher is defined, as are the qualities, skill and expertise necessary for the job. Guidelines for staff selection are listed under four categories: (1) education, (2) experience, (3) present level of knowledge/skill, (4) general reference ability, Three types of staff training programs are listed: (I) general orientation for all staff (2) training in the fundamentals of online searching, and 3) online searcher development and training. Content requirements !or each of these programs are provided. The need for well planned staff selection and development methods is acute if quality online search service is to be provided in public libraries.  相似文献

Summary

Digital reference is an important research area with the potential to enhance information delivery to library patrons. The process of digital reference involves the challenges and problems of an interactive computer-mediated reference interview. Related studies of mediated online searching have identified the major tasks during a mediated online search. The search intermediary's tasks included gathering information on the information need, previous searches on the topic by the information seeker, search terms and strategies, database selection, search procedures, system's outputs and relevance of retrieved items, and the number of topics to be searched. The information seeker's tasks include providing information to the search intermediary on their topic, discussing their previous information seeking and evaluating the online search output. Models of digital reference interviews need to include more complex information seeking behaviors, such as successive searching and multitasking. Further research is needed to extend our understanding of digital reference processes.  相似文献

The primary role of the clinical medical librarian (CML)--locating and providing quality-filtered, patient-specific information to physicians--has been questioned recently because of the dramatic rise in end-user searching. This study administered a questionnaire to evaluate the current impact of this service in a major hospital setting with a long established CML program. The study showed that the CML provided house officers with information that affected patient care (defined as diagnosis, diagnostic tests, or treatment) between 40% and 59% of the time. This was true even though most physicians reported they generally researched the question prior to consulting the CML. In addition, the house officers in this study indicated that they distributed the CML-provided information to other health care providers 56%-96% of the time. Based on these limited results, it appears that CMLs can continue to provide information that has a strong impact on patient care, despite the availability of an end-user local MEDLINE system.  相似文献
