The ability to search bibliographic databases effectively is now an essential skill for anyone undertaking research in health. This article discusses the way in which databases are constructed and some of the important steps in planning and carrying out a search. Consideration is given to some of the advantages and limitations of searching using both thesaurus and natural language (textword) terms. A selected list of databases in health and medicine is included. (+info)
Bibliometric methods for the evaluation of arthritis research.
This study uses bibliometric methods to evaluate the magnitude and quality of publications in arthritis research in the UK and compare this with that of other countries. Arthritis research was defined by publication in a specialist journal or by specific title key words or address. Outputs from 13 countries between 1988 and 1995 were analysed by number, research level (from clinical to basic) and potential impact on other researchers (from low to high). The UK has a strong presence in arthritis research and the highest relative commitment of all the countries studied. UK output was more clinical than that of other countries, except Spain, and was of relatively high impact. A second study examined UK arthritis papers supported by different funding sources, including government, private-non-profit and industry. Papers with funding acknowledgements were of significantly higher impact and less clinical than those without. The Arthritis Research Campaign was the leading funder in the UK with high-impact papers which, over the 8 yr period, have become more clinical than those supported by other funding sources, except hospital trusts.

Making sense of the electronic resource marketplace: trends in health-related electronic resources.
Changes in the practice of medicine and technological developments offer librarians unprecedented opportunities to select and organize electronic resources, use the Web to deliver content throughout the organization, and improve knowledge at the point of need. The confusing array of available products, access routes, and pricing plans makes it difficult to anticipate the needs of users, identify the top resources, budget effectively, make sound collection management decisions, and organize the resources effectively and seamlessly. The electronic resource marketplace requires much vigilance, considerable patience, and continuous evaluation. There are several strategies that librarians can employ to stay ahead of the electronic resource curve, including taking advantage of free trials from publishers; marketing free trials and involving users in evaluating new products; watching and testing products marketed to the clientele; agreeing to beta test new products and services; working with aggregators or republishers; joining vendor advisory boards; benchmarking institutional resources against five to eight competitors; and forming or joining a consortium for group negotiating and purchasing. This article provides a brief snapshot of leading biomedical resources; showcases several libraries that have excelled in identifying, acquiring, and organizing electronic resources; and discusses strategies and trends of potential interest to biomedical librarians, especially those working in hospital settings.

Interlibrary cooperation: from ILL to IAIMS and beyond.
A recent solicitation over the MEDLIB-L e-mail discussion list revealed over thirty diverse examples of hospital library-based interlibrary cooperative initiatives currently underway. Many are familiar and have been featured in the professional literature. Most go unreported and unrecognized however, comprising invisible resource-sharing infrastructures that hospital librarians painstakingly piece together in order to provide their clients with expanded service options. This paper, drawing from the MEDLIB-L survey as well as descriptions in the published literature, provides a broad overview of such recent interlibrary cooperative efforts. Examples include interlibrary loan networks, collective purchasing initiatives, holder-of-record or union catalog access agreements, arrangements to provide e-mail and Internet access, and consortia to share electronic resources. Examples were chosen based on the initiatives' diversity of participants, and represent a wide range of locations across the United States. Such initiatives focus on local, statewide, or regional collaboration, and several involve partnerships between academic medical center libraries and regional hospital libraries. An early example of a hospital-based interlibrary cooperative IAIMS effort is described, pointing to future possibilities involving the Internet and regional hospital system intranets. (+info)
UCMP and the Internet help hospital libraries share resources.
The Medical Library Center of New York (MLCNY), a medical library consortium founded in 1959, has specialized in supporting resource sharing and fostering technological advances. In 1961, MLCNY developed and continues to maintain the Union Catalog of Medical Periodicals (UCMP), a resource tool including detailed data about the collections of more than 720 medical library participants. UCMP was one of the first library tools to capitalize on the benefits of computer technology and, from the beginning, invited hospital libraries to play a substantial role in its development. UCMP, beginning with products in print and later in microfiche, helped to create a new resource sharing environment. Today, UCMP continues to capitalize on new technology by providing access via the Internet and an Oracle-based search system providing subscribers with the benefits of: a database that contains serial holdings information on an issue specific level, a database that can be updated in real time, a system that provides multi-type searching and allows users to define how the results will be sorted, and an ordering function that can more precisely target libraries that have a specific issue of a medical journal. Current development of a Web-based system will ensure that UCMP continues to provide cost effective and efficient resource sharing in future years. (+info)
Mapping the literature of dental assisting.
The purpose of this study was to identify core journals and the databases that provide access to these journals for the field of dental assisting. This study was completed as a part of the Medical Library Association (MLA) Nursing and Allied Health Resources Section's project to map the literature of allied health. There were three original journals selected for analysis using the prescribed methodology, Dental Assistant, the journal of the American Dental Assistants Association; Journal of the CDAA, the journal of the Canadian Dental Assistants' Association; and Dental Teamwork, published by the American Dental Association. Dental Teamwork ceased publication in December 1996; however, it was considered a necessary part of the analysis due to its extensive coverage of dental assisting as well as its numerous scientific articles with references. In Dental Assistant, there were 16 source articles, containing 206 citations. In Dental Teamwork, there were 31 source articles with 308 citations. In Journal of the CDAA, there were only 3 source articles with 14 citations. Bradford's Law of Scattering was applied to the journal citations. Four databases, MEDLINE, the Cumulative Index to Nursing and Allied Health Literature, EMBASE/Excerpta Medica, and HEALTH were analyzed for their coverage of these cited journals. This study may encourage the dental assisting profession to take a close look at its existing journals and to consider enhancing the content of these journals or the publication of additional journals in the field. Dental assistants of today need substantive literature that deals with all aspects of their chosen profession in order to meet the challenges of providing dental health care in the future. (+info)
Mapping the literature of dental hygiene.
Despite the long history of the dental hygiene profession, little research has been conducted on the characteristics of its literature. In this study, the bibliometric method was used to identify the core journals in the discipline and the extent of indexing of these journals. The study was a part of the Medical Library Association (MLA) Nursing and Allied Health Resources Section's project to map the allied health literature. Five journals were found to provide one-third of all references studied. Forty-two journals yielded an additional one-third of the references. MEDLINE had the best indexing coverage with 87% of the journals receiving indexing for at least one-half of the articles included. Limited coverage was provided by EMBASE/Excerpta Medica (11%) and the Cumulative Index to Nursing and Allied Health Literature (9%). The findings identified titles that should be added by indexing services as well as those that should have more complete coverage. (+info)
Mapping the literature of diagnostic medical sonography.
Diagnostic medical sonography has been evolving as a recognized allied health occupation since the early 1970s, but no bibliometric studies of the literature of the field have been published. This study, part of the Medical Library Association Nursing and Allied Health Resources Section's Project for Mapping the Literature of Allied Health, attempted to identify the core journals in diagnostic medical sonography and determine how well these journals are indexed by MEDLINE, EMBASE/Excerpta Medica, and the Cumulative Index to Nursing and Allied Health Literature (CINAHL). Citation analysis was done using the three journals listed for the field by the Brandon/Hill list. Characteristics of two of these three journals affected the results to the extent that more data should be gathered to reach conclusions about the literature of diagnostic medical sonography as a whole. Results of the analysis do suggest that the literature of echocardiography, which is a special area of diagnostic medical sonography, is indexed much more completely by MEDLINE and EMBASE/Excerpta Medica than by CINAHL. Suggestions are made for librarians making collection development decisions in this area of allied health. (+info)
