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

Library integration into the medical school curriculum is a crucial aspect of meeting Liaison Committee on Medical Education (LCME) Accreditation Standards and the Association of American Medical Colleges (AAMC) Medical School Objectives Project (MSOP) guidelines. To accomplish this, academic health sciences libraries seek to develop evidence-based medicine (EBM) literature searching classes within the medical school curriculum. Establishing a basic understanding of the fundamental concepts behind health sciences database searching among medical students is a prerequisite for a more demanding evidence-based literature searching curriculum. The George T. Harrell Health Sciences Library, Penn State College of Medicine, sought to incorporate an evidence-based medicine literature searching structure by working within the existing problem-based learning system during the preclinical years. Students in the clinical years will participate in evidence-based assignments during their rotations. A fourth-year EBM elective will be created to reinforce and round out students' exposure to these concepts.  相似文献

Public Health England plays a vital role in ensuring the health of the nation. The Knowledge and Library Service (KLS) is a key part of the organisation's evidence supply chain. KLS staff handle over 200 requests for literature searches per annum, and this number is increasing exponentially year on year. Searches are often complex and require specialist public health knowledge to complete effectively. Library staff who are new to the area of public health require support and training. In this article, Anh Tran, Knowledge and Evidence Specialist for Public Health England, discusses a peer supported literature search training course that has been developed in‐house for the benefit of new library staff, and to increase the Knowledge and Library Service's literature searching capacity at Public Health England.

Library faculty members at the Health Sciences Library at the LSU Health Shreveport campus offer a database searching class for third-year medical students during their surgery rotation. For a number of years, students completed “ten-minute clinical challenges,” but the instructors decided to replace the clinical challenges with innovative exercises using The Edwin Smith Surgical Papyrus to emphasize concepts learned. The Surgical Papyrus is an online resource that is part of the National Library of Medicine's “Turning the Pages” digital initiative. In addition, vintage surgical instruments and historic books are displayed in the classroom to enhance the learning experience.  相似文献

OBJECTIVES: Medical Library Association (MLA) members were surveyed to gather background about the current state of expert searching in institutions. The survey results were intended to guide the recommendations of the Task Force on Expert Searching for promoting the importance of expert searching and implementing those recommendations. METHODS: MLA members were surveyed, and data obtained from the survey were compiled and analyzed to answer three general questions: what is the perceived value of searching skills to the institution, how do health sciences librarians maintain and improve their searching skills, and how are searching services promoted and/or mandated in the institution. RESULTS: There were 256 responses to the survey. Over 95% of the respondents saw their expert-searching skills were of value to their institutions, primarily through performing mediated searches and search consultations. Over 83% of the respondents believed that their searching skills had improved over the past 10 years. Most indicated that continued training was very important in maintaining and improving their skills. Respondents promoted searching services most frequently through orientations, brochures, and the libraries' Web pages. No respondent's institution mandated expert searching. Less than 2% of respondents' institutions had best practice guidelines related to expert searching, and only about 8% had guidelines or policies that identified situations where expert searching was recommended. CONCLUSIONS: The survey supports the belief that health sciences librarians still play a valuable role in searching, particularly in answering questions about treatment options and in providing education. It also highlights the need for more expert searching courses. There has been minimal discussion about the perceived need for expert-searching guidelines in the institutions represented by survey respondents.  相似文献

ABSTRACT

This article looks at two different projects, the Google Book Search project and the Text Creation Partnership, both linked to the University of Michigan Library. Though on the surface they are very different, the Text Creation Partnership, a model of cooperation between scholars, librarians, and publishers, may have some useful lessons for how to make Google Book Search more useful for academic research, particularly in full-text searching.  相似文献

This article examines the writing of Thomas Mann, Reference Librarian at the Library of Congress, regarding the enduring value of traditional methods and tools of research libraries, particularly online public catalogs, professional cataloging, and Library of Congress Subject Headings and pre-coordinated subject strings. One major contention asserted by Mann is that keyword searching on the Internet, while very valuable when used judiciously, should not be used as a substitute for traditional catalogs and cataloging. Also examined are the deprofessionalization of cataloging, inadequate ideas about library users, dangers to serious research, digitization, and the enduring value of books.  相似文献

Objective:The decisions and processes that may compose a systematic search strategy have not been formally identified and categorized. This study aimed to (1) identify all decisions that could be made and processes that could be used in a systematic search strategy and (2) create a hierarchical framework of those decisions and processes.Methods:The literature was searched for documents or guides on conducting a literature search for a systematic review or other evidence synthesis. The decisions or processes for locating studies were extracted from eligible documents and categorized into a structured hierarchical framework. Feedback from experts was sought to revise the framework. The framework was revised iteratively and tested using recently published literature on systematic searching.Results:Guidance documents were identified from expert organizations and a search of the literature and Internet. Data were extracted from 74 eligible documents to form the initial framework. The framework was revised based on feedback from 9 search experts and further review and testing by the authors. The hierarchical framework consists of 119 decisions or processes sorted into 17 categories and arranged under 5 topics. These topics are “Skill of the searcher,” “Selecting information to identify,” “Searching the literature electronically,” “Other ways to identify studies,” and “Updating the systematic review.”Conclusions:The work identifies and classifies the decisions and processes used in systematic searching. Future work can now focus on assessing and prioritizing research on the best methods for successfully identifying all eligible studies for a systematic review.  相似文献
