MELVYL MEDLINE: a library services perspective

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.     

OneSearch in a dental library: beyond MEDLINE.

MEDLINE, which includes the Index to Dental Literature, has been the database of choice for most search requests generated at Indiana University School of Dentistry. However, many requests extend beyond dentistry and the health sciences into the realms of business, education, psychology, law, and computer technology. For these requests, DIALOG's new OneSearch feature can be a simple and cost-effective mechanism for supplementing searches that would otherwise be confined to MEDLINE.

An evolution of experts: MEDLINE in the library school.

Question: What is the real value that medical librarians bring to the health care environment? How have library science educators, frequently former practitioners themselves, responded to the challenge of expert searching?Methods: In this paper, I give an historical introduction to the landscape of medical information retrieval through the development of MEDLINE. I then look at the evolution of training in online searching and its place in the context of library school education and particularly the effect of generalist education on future specialists. Finally, I acknowledge the new role of the informationist as another assertion of our professional expertise.Conclusions: The three interdependent subsystems of our professional machine—our schools, our association, and our professional peers— must all respond to this challenge by asserting our expertise in our curricula, in our continuing education, and in our dialogues with each other. Only by acknowledging the interaction of these subsystems will real and positive changes be effected to benefit our profession and our constituencies.     

A user study of manual and MEDLINE literature searches in the hospital library

To determine possible uses for MEDLINE in the hospital library, health practitioners requesting literature searches were provided with both a manual and a MEDLINE search. Patron receptivity to MEDLINE was good, but the manual search was more often preferred. The health practitioners responding to a questionnaire apparently had delegated literature searching and evaluation of material to the hospital librarians, especially when clinically related information was needed. In the community hospitals where both the search and the selection of material are the responsibility of the librarian, MEDLINE can be used as the primary search tool or to supplement material provided.     

Subpoenas and library operations: rules and recourse

The subpoena process represents a legal obligation and duty of citizenry and is becoming a fact of life in the operations of many libraries. Regardless of whether a library is directly involved in litigation, the library director may be faced with adjusting operations to compensate for the loss of personnel, collection materials, or other resources in order to accommodate the demands of a subpoena. This paper outlines the formal subpoena process and highlights a number of scenarios by which the library may become a part of the process. The area of computer law, in particular, may present a "growth phase" in library litigation. In addition, recommendations to minimize the service interruptions caused by the subpoena are offered. The director must assist library counsel in formulating a response to challenge, modify, or quash (throw out) the subpoena. Efforts to quash the subpoena require proof that the materials requested are irrelevant to the case, not subpoenaed for "good cause," or that compliance would be unduly oppressive and burdensome. In any case, the library director must be fully prepared to educate counsel on the potential impact of the subpoena.     

The review article in MEDLINE: ambiguity of definition and implications for online searchers

The definition of a "review article" is examined from the viewpoints of the National Library of Medicine and of the patron. Implications of the differing interpretations of "review article" are discussed and possible alternative online search strategies are presented.     

MEDLINE training within the library school curriculum: quality control and future trends.

In order to assess the current status of MEDLINE training provided by schools of library science, a survey was conducted of those schools having an educational identification code issued by the National Library of Medicine. Information was gathered on such variables as the instructors' background and preparation, the course objectives and content, and the amount of on-line experience provided to students in each of eleven programs. An evaluation of these measures indicates that more opportunities to gain experience in using MEDLINE should be initiated by library schools and that current efforts should be continued and expanded. Specific recommendations for accomplishing these goals are outlined; they are addressed to health sciences librarians, library school educators, the Medical Library Association, and the National Library of Medicine.     

MEDLINE and PsycLIT on CD-ROM: a survey of users in an academic medical library

A survey of users of PsycLIT and MEDLINE on CD-ROM was performed at an academic medical library. The questionnaire was designed to gather information about the user population, satisfaction of the users, the assistance needed to use the systems, and the type of searches being performed. The majority of users were graduate students in the schools of medicine, nursing, and pharmacy. In general, users were satisfied with the performance of the systems. Assistance from a librarian, printed documentation, or another patron was required by 85% of users, and they were generally satisfied with this assistance. Most searches were performed to obtain information on a subject. The results were remarkably similar for both databases.     

Research governance: implications for health library and information professionals

The Research Governance Framework for Health and Social Care published by the Department of Health in 2001 provides a model of best practice and a framework for research in the health and social care sector. This article reviews the Department of Health Research Governance Framework, discusses the implications of research governance for library and information professionals undertaking research in the health- and social-care sector and recommends strategies for best practice within the information profession relating to research governance. The scope of the Framework document that covers both clinical and non-clinical research is outlined. Any research involving, amongst other issues, patients, NHS staff and use or access to NHS premises may require ethics committee approval. Particular reference is made to the roles, responsibilities and professional conduct and the systems needed to support effective research practice. Issues such as these combine to encourage the development of a quality research culture which supports best practice. Questions arise regarding the training and experience of researchers, and access to the necessary information and support. The use of the Framework to guide research practice complements the quality issues within the evidence-based practice movement and supports the ongoing development of a quality research culture. Recommendations are given in relation to the document's five domains of ethics, science, information, health and safety and finance and intellectual property. Practical recommendations are offered for incorporating research governance into research practice in ways which conform to the Framework's standards and which are particularly relevant for research practitioners in information science. Concluding comments support the use of the Research Governance Framework as a model for best practice.     

Patient education and health outcomes: implications for library service

Many librarians take an active role in patient education, for practical and ethical reasons; however, it is important to examine the effect of such activities on health outcomes. Although the rationale for patient education is that increased knowledge leads to a change in attitude that in turn affects behavior, studies have shown that this is not always true. Furthermore, other studies have shown that patient education programs by themselves have no lasting influence on patient compliance with therapy that has been linked to improved health. Librarians should examine a variety of reasons for their involvement in patient education activities. For librarians who accept improved patient compliance as a goal, specific recommendations based on literature review are made to help implement effective strategies.     

MEDLINE and MeSH

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.     

Medicine and health care: implications for health sciences library practice

The American health care system is experiencing a period of unprecedented change. This paper identifies and discusses the major changes in patient care, research, control of the health care system, and medical education, and their implications for health sciences librarians. These changes have resulted in new demands for effective information delivery and a broader health sciences library clientele. There are both challenges and opportunities for health sciences librarians as they respond to information pressures of the current health care environment and anticipate future needs.     

Testing the new technology: MEDLINE on CD-ROM in an academic health sciences library.

The UCLA Biomedical Library tested a six-month portion of the MEDLINE database on compact disc to determine its potential application in a large, university health sciences library environment. Patron response to the system, previous search experience, and actual search strategies were recorded. Although the overwhelming user response was positive in spite of little previous experience with online searching, results show underutilization of the system because of both software and hardware problems. The implications of this test underline the important role libraries must take in guaranteeing that new reference tools like CD-ROM be made genuinely user-friendly.     

MELVYL MEDLINE: reference service implications of an end-user search system.

The implementation of MELVYL MEDLINE, a successful online end-user system in the University of California (UC) health sciences libraries greatly enhanced the capabilities of reference desk service by providing immediate access to current medical literature from the MEDLINE database. With these enhancements, the extent of the impact on the delivery of reference service was not anticipated. Concurrent with providing traditional reference service requests, there was a constant need for individualized end-user instruction by MELVYL MEDLINE users, and continual maintenance of workstation equipment and supplies. This paper describes the experiences at the UC Irvine (UCI) Biomedical Library and compares these experiences with other UC health sciences libraries. The purpose of this paper is to discuss some of the issues which must be considered when planning for the implementation of an end-user system within the reference service function.     

Computerisation of library operations in Singapore: An overwiew

This paper traces the development of computerisation of library operations in Singapore from 1970–1989. Two levels of computerisation are examined, namely:

• (i) institutional level, and

• (ii) network or national level.

At the institutional levels, the National Library, National University of Singapore Library, Nanyang Technological Institute Library, Singapore Polytechnic Library, Ngee Ann Polytechnic Library, the Law Libraries Consortium, the Education Libraries Consortium and the ECOMNET Libraries Consortium are among the major libraries examined. At the network level, the development and progress, functions and organisation of the Singapore Integrated Library Automation Service (SILAS) are outlined. The author concludes that computers and related technologies are becoming increasingly important in the library scene of Singapore and that there is no perfect library computer system and upgrading is a necessary continuous process.

A rural virtual health sciences library project: research findings with implications for next generation library services

PURPOSE: The Shared Hospital Electronic Library of Southern Indiana (SHELSI) research project was designed to determine whether access to a virtual health sciences library and training in its use would support medical decision making in rural southern Indiana and achieve the same level of impact seen by targeted information services provided by health sciences librarians in urban hospitals. METHODS: Based on the results of a needs assessment, a virtual medical library was created; various levels of training were provided. Virtual library users were asked to complete a Likert-type survey, which included questions on intent of use and impact of use. At the conclusion of the project period, structured interviews were conducted. RESULTS: Impact of the virtual health sciences library showed a strong correlation with the impact of information provided by health sciences librarians. Both interventions resulted in avoidance of adverse health events. Data collected from the structured interviews confirmed the perceived value of the virtual library. CONCLUSION: While librarians continue to hold a strong position in supporting information access for health care providers, their roles in the information age must begin to move away from providing information toward selecting and organizing knowledge resources and instruction in their use.
