Bibliography of Bioethics and Index Medicus: comparison of coverage, publication delay, and ease of recall for journal articles on bioethics 总被引：1，自引：0，他引：1
S S Marsh 《Bulletin of the Medical Library Association》1987,75(3):248-252
Citations selected from the bibliographies of recent texts, a specialized subject bibliography, and review articles were checked in both Cumulated Index Medicus (IM) and the Bibliography of Bioethics (BB) to compare coverage, publication delay, probable causes of indexing and retrieval failure, and the ease with which relevant citations were retrieved. The study also attempted to determine whether BB included appropriate articles from the MEDLINE database in a timely and systematic manner. While 98% of the IM citations appeared within a year of publication, 79% of the BB citations appeared two to three years after their publication dates. The average citation appeared twice as frequently in IM as in BB. 相似文献

We compared Index Medicus and Drug Literature Index during a search concerning the toxicity of eight drugs used in treating tropical diseases. Indexes covering the years 1969, 1970, and 1971 were searched. Index Medicus produced 198 citations and Drug Literature Index 309. There were seventy citations that appeared in both indexes, a duplication of 16%. Highest percentage of duplication for any one drug was 38.9%. We concluded that Index Medicus and Drug Literature Index provide complementary coverage in the area of drug toxicity and that, therefore, both tools should be consulted in searches of this nature. 相似文献

The Missouri Institute of Psychiatry Library has implemented an inexpensive, manual SDI (Selective Dissemination of Information) service based upon the monthly issues of Index Medicus. The implementation and refinement of the system are documented, and the very favorable response to the system is examined. The SDI service is compared to Current Contents, with the finding that 60 percent of the SDI participants prefer it to Current Contents. For this select portion of researchers the Index Medicus SDI is the more suitable mode of current awareness. For a significant portion of the MIP staff, however, the scope of Index Medicus is too restricted to suitably replace Current Contents. All SDI users find it a highly acceptable current awareness service for use in addition to Current Contents and have indicated the desire to continue participation in the service. 相似文献

Many factors are weighed in judging the quality of a journal. Editorial policies in the instructions to authors section offer an important, though often neglected, source of information. In addition to directions on formatting and style, this section often includes financial disclosures and policies on coverage, peer review, confidentiality, human experimentation and duplicate submissions. This study analyzes the contents of instructions sections from several categories of medical journals to determine their usefulness in making collection development decisions. Included are journals currently considered the most prestigious, indexed in Index Medicus and Abridged Index Medicus, and not indexed in Index Medicus or subscribed to by a typical large academic health sciences library. It was found that in a statistically significant number of journals, the instructions to authors section is more likely to be included and substantive in highly regarded journals than in less prestigious journals. It is concluded that the amount of information in the instructions section is related to the quality of the journal and that these sections are a useful collection development tool. 相似文献

Rehabilitation professionals need access to current journal literature for research and patient care. Using the American Journal of Occupational Therapy, subject headings from the MEDLINE and NAHL files are compared to determine coincidence and numbers of headings. Based on the study findings, an information retrieval plan is suggested that librarians may use in assisting rehabilitation personnel in effective use of Index Medicus, Cumulative Index to Nursing and Allied Health, and their online counter-parts. 相似文献

The main criterion for selecting journals for indexing in Index Medicus, and thereby largely in MEDLARS, is quality. Subject scope varies with the voiced needs of the biomedical community. The Index aims to cover the best journals in all relevant subject fields, but the percentage of journals on a subject indexed depends on the quality of each journal. Country and language coverage depends on quality, even in the case of the best journals of each, although American biases may affect such selection. While a number of guidelines exist for identifying quality journals, information necessary to apply them confidently is often difficult to obtain. The National Library of Medicine is advised by an Ad Hoc Panel on the Selection of Journals for Index Medicus, composed both of NLM officers and extramural members. Criticism has been voiced that too many titles are indexed, compared with titles actually used, but no meaningful statistics of use exist which can identify titles which should be excluded from indexing. Continuing suggestions from users regarding titles indexed would benefit everyone. 相似文献

When the National Library of Medicine acquired a computer to augment its publication program, the intent was to present in one medium an index to journal articles and a catalog of books and new serial titles. The computer programs designed for indexing were unsatisfactory for cataloging, however; so two publications were issued, the Index Medicus and the NLM Current Catalog.The Current Catalog features separate name and subject sections, added volumes, and technical reports.The Express Cataloging Service was one of the first attempts to increase the speed and coverage of the Catalog. Shared cataloging with the Library of Congress, the Countway Library at Harvard, and the Upstate Medical Library in Syracuse, New York, have also contributed to the efforts toward improving this library service. An additional shared cataloging program, this time with the National Medical Audiovisual Center, is expected to be implemented shortly. 相似文献

This study reports on the editorial peer review practices of two categories of U.S. medical journals indexed in Index Medicus. Journals in group 1 were included on each of three lists of recommended journals, had a circulation of 10,000, and were cited at least 5,000 times per year. Group 2 journals, also indexed in Index Medicus, met none of the criteria. After being pretested, data were collected through a series of interviews and questionnaires. A summary of the methodology and an analysis of the differences between data collected through questionnaires and interviews is reported. The study concluded that initial interviews are very helpful in designing a questionnaire; a high percentage of editors agreed to be interviewed (100% for sixteen group 1 editors and 93.8% for sixteen group 2 editors); a 69.4% response rate to the mailed questionnaire indicates either sufficient follow-up or a high rate of interest in the subject matter; no trends identified by the questionnaire were reversed by changes in answers given during the interviews; approximately 11% to 15% of the answers differed between the questionnaire and interview methodology; and for some sensitive issues, editors were more likely to give answers on the questionnaire according to what was perceived as the most appropriate answer, rather than the actual practices of the journal. 相似文献

This study demonstrates the growth of medical periodical literature by means of the increase of titles indexed in the Index-Catalogue and in Index Medicus, with reference to other biomedical-related titles not covered in these publications. Stress is laid on the fact that information outside the biomedical area is needed by the researcher. Problems of information retrieval, with the specific needs of the user in mind, are discussed, together with the particular problems of indexing which this specificity raises. 相似文献

Lister Hill Center is concerned with developing a computerized information system, with a data base consisting of an expanded Abridged Index Medicus, using part of a large computer system, and connecting this system to the TWX network. With this in view, a study was made of the demands on such a network, and a study of the SUNY network showed that on-line access more than doubled the use of the data base.Other alternatives to the TWX system are described. 相似文献

Journal article overlap is defined as the same journal article being indexed by two or more services. Using journal references from seventy dissertations written in the preclinical sciences, the extent of journal article overlap among Index Medicus, Science Citation Index, Biological Abstracts, and Chemical Abstracts was examined. Of the 7,969 journal references cited, 92% were indexed by at least two of these services; 591 articles were covered by only one of the services, and 55 articles were not indexed. A discussion of the advantages and costs of journal article overlap is presented. 相似文献

An overlap study was performed to identify important psychology journals that are also of interest to biomedical scientists and health care practitioners. The journal lists of Index Medicus, Hospital Literature Index, Cumulative Index to Nursing and Allied Health Literature, and International Nursing Index were compared with the journal list of Psychological Abstracts. A total of 357 Psychological Abstracts titles were also in one or more of the health sciences indexes. A core list of forty-five titles covered by all of the indexes is presented in the Appendix. Results of the study are discussed vis-à-vis cooperative serials acquisition and retention efforts. 相似文献

ABSTRACTThis study is an exploration of how Association of Research Libraries (ARL) member institutions encourage and support their librarians engaged in research and publication. Using an online survey sent to members of the ARL library directors’ listserv, the authors gathered information about the role of research and publication in the respondents’ evaluation systems, the approaches used to support this activity, the respondents’ own records of research and publication, and their opinions about which approaches have the most impact. The results indicate that funding, time, and mentoring are the most frequently used approaches to promote research and publication productivity. 相似文献

This article provides a brief history of the development of the MEDLINE database and its huge impact within the UK, from its inception to the present time. The origins of MEDLINE can be traced back to a collection of books in the US Surgeon General's Office during the American Civil War and John Shaw Billings' decision, during 1867, to make this Library as complete as possible. From these beginnings, Index Medicus was developed in the early years of the 20th century, and electronic versions of the database began with the computerized on-demand search service MEDLARS in 1964 and then via CD-ROM and Internet Grateful Med to the web-based and free-to-all service, PubMed, in 1997. The response to PubMed was immediate and startling with usage increasing from 7 million searches per annum in 1996 to 400 million searches per annum in 2001 and the service continues to improve. MEDLINE providers are now offering mapping of natural language queries to the sophisticated indexing vocabulary (Medical Subject Headings, MeSH) and the provision of specific filters for different types of publication to improve searching efficiency, as well as links to full-text versions of the papers where available. The next steps are likely to involve an increased blurring of database and full-text boundaries, incorporating seamless access to the best available evidence within MEDLINE and a wide range of other information resources within a single search and to an increasing amount of full-text via various open-archive initiatives. As ever, the US National Library of Medicine is in the vanguard of research and further applications of its MEDLINE database for users within the UK will be awaited with great interest. 相似文献

This study investigates beliefs about the determinants of suchbehavioral characteristics as intelligence, athleticism, obesity,and alcoholism by asking respondents to the 2004 General SocialSurvey to rate vignettes describing individuals exhibiting thesecharacteristics along a 21-point scale ranging from completegenetic determination to complete environmental determination.The vignettes systematically varied the social desirabilityof the characteristic as well as the race and gender of theperson exhibiting it. We analyzed the effect of the carefullycounterbalanced vignette characteristics and the correspondingrater characteristics on respondents’ ratings of the vignettes,hypothesizing that these ratings would reflect mechanisms ofclaiming credit for desirable characteristics and avoiding blamefor undesirable ones. Contrary to our expectations, we foundno effect of any of the vignette characteristics on the ratings,and only two significant main effects of respondent demographiccharacteristics: Black respondents were more likely to use geneticratings; and better educated respondents, environmental ones.

From the inception of the first Index Medicus, published in 1879, to the present, the National Library of Medicine has been concerned with the quality of journals in the Index. The Library has, therefore, sought advice repeatedly on how best to maintain currency of the Index without sacrificing quality and subject matter balance.Responding to suggestions, the Library decided in June 1964 to base its selection of journals on recommendations made by a panel consisting primarily of extramural consultants widely regarded as specialists in the totality of biomedical literature. Beginning with its first meeting in September 1964, this panel has been fortified in its reviews by advice from subject matter specialists. The panel, by its own wishes, which bear the endorsement of the Board of Regents of the Library, will continue to rely heavily on such expert advice in future evaluations of journals. 相似文献
