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

This is the third part of a comprehensive, quantitative study of biomedical book reviewing. The data base of the total project was built from statistics of 3,347 reviews of 2,067 biomedical books appearing in all 1970 issues of fifty-four reviewing journals. This part of the study explores the duplication patterns in book reviewing among these media. It is found that 35.17% (727 books) of the 2,067 titles were reviewed more than once in 1970, these titles accounting for 2,007 of the total of 3,347 reviews. For the most part, reviews of the most frequently reviewed titles appeared in such journals as British Medical Journal, Annals of Internal Medicine, Lancet, Journal of the American Medical Association, and New England Journal of Medicine. These five journals covered 93.53% of the 727 books reviewed more than once in 1970. 相似文献

In this paper we map the scientific journals from Ibero‐American countries indexed in the Web of Science and Scopus. Data were collected from the journals' websites. Of 879 journals in the two databases, Spain accounted for 35.6% of the titles, Brazil 28.5%, and the remaining 11 countries together 35.9%. Medicine had the most titles in almost all countries, with 28.9% of the total, followed by agricultural and biological sciences (particularly in Brazil) with 14.9%, and social sciences with 11.5%. A digital format was used by 95% of the journals and 82% were open access, with an even higher level of open access in Latin America. The publishers were mainly universities (37.7%) and associations (31.1%). Ibero‐American countries, with the exception of Spain, do not have a long tradition as scientific journal publishers, but in the last few years they have gained in importance as players in scientific communication with the use of new business models for journals. 相似文献

??There exists a great fap in organizing and using book reviews between the Chinese and American Libraries. American Librarians rely greatly on book reviews in book selection. but they are encouraged to search for more book information in database now. In China, however, neither reviewing activities nor book rebiew journals and indexes corresponding to the needs of library circles have been fully developed. With the development of the publish industry and the drastic increase of book titles, it becomes especially improtant to strengthen the role of book review in library collection building. 相似文献

This study in an academic medical sciences library setting examines the correlation of usage of a matched set of print and online titles, the validity of e-journals usage statistics and the impact of online journals on print journal usage. The print and online usage was determined for 270 journals, both versions of which were available. Print usage was determined annually since 1997 using the reshelving and the error-copies method. Online usage statistics were delivered by five publishers and corrected for redundant multiple accesses. Print journal usage decreased by 22.3 and 30.2% respectively over each of 2 years after the introduction of online journals. Journals published both in print and online lost 30.4% of their print usage within 2 years. The total loss of usage of print-only titles in the same period was somewhat higher, at 45.8%. The average correlation between online and print usage is 0.60 and 0.67 respectively. For the examined titles, users accessed the online versions ten times as often as the print version. Two clearly distinguishable groupings emerged: while with Academic Press and Elsevier, e-journal usage exceeded print usage by a factor of 3 or 4, the e-journals of Blackwell, HighWire and Springer were used on average 14.6 times as frequently as the corresponding print journals. Each usage of a print article cost 2.79-50.82 Euro, each usage of an online article 0.31-15.10 Euro, depending on the publisher. On average, the usage of an online article was 5.4 times cheaper. Within 2-3 years the usage of online journals has outstripped that of print titles by a factor of ten, but the specific spectrum of usage remains much the same as when only print journals alone existed. Print titles not available online suffer a greater decline in usage compared with print/online journals. This confirms that what is read or purchased is determined primarily by ease of access and that there is a steady tendency to reduce the multiplicity of access modes to a manageable few. The availability of journals online seems to have created a new clientele, at least in the case of the German-language Springer journals. The connection between supplier and supply is much less clear with e-journals than it is with print titles. Therefore it is very important to stress and encourage the role of the library as the supplier of this sort of information in the university environment. Collection building issues are discussed in the light of the results. 相似文献

Creating up-to-date listings of electronic journals is challenging due to frequent changes in titles available and in URLs for electronic journal titles. However, many library users may want to browse web pages which contain listings of electronic journals arranged by title and/or academic disciplines. This case study examines the development of a system which automatically exports data from the online catalog and incorporates it into dynamically-generated web sites. These sites provide multiple access points for journals, include web-based interfaces enabling subject specialists to manage the list of titles which appears in their subject area. Because data are automatically extracted from the catalog, overlap in updating titles and URLs is avoided. Following the creation of this system, usage of electronic journals dramatically increased and feedback has been positive. Future challenges include developing more frequent updates and motivating subject specialists to more regularly monitor new titles. 相似文献

The economic plight of the 1970s often limits the librarian, who should be the final selector, to insufficient funds for acquiring essential publications. The librarian, in addition to making every effort to acquire the best possible collection, must provide access from other libraries, within and outside one's parent institution, to materials not acquired; for this purpose, an effective document delivery network has proved more significant than formal plans for shared acquisitions. Too much is published, but the choices become more manageable with selection criteria that include limiting subject scope and keeping within the English language. In regard to journals, new titles should be added only reluctantly; cancellation lists compiled with the help of selective lists, the librarians' judgment, and users' responses; and newsletters and state journals pruned to a mimimum. As to books, selective lists should be consulted; congress proceedings generally ignored; and reprinted collections, multiple copies, and gifts considered with care. Book reviews are more useful selection aids now that lack of funds causes delays in purchasing than when new titles were acquired promptly with less discrimination. Audiovisual media, although widely pushed, do not replace printed materials, are not of central importance to many faculties, are expensive, and thus comprise a bandwagon which the impoverished library cannot afford to board without extra funding. The less money there is, the more need for a librarian's selection skills. 相似文献

The major purpose of this study was to identify and assess indexing coverage of core journals in cytotechnology. It was part of a larger project sponsored by the Nursing and Allied Health Resources Section of the Medical Library Association to map the literature of allied health. Three representative journals in cytotechnology were selected and subjected to citation analysis to determine what journals, other publication types, and years were cited and how often. Bradford's Law of Scattering was applied to the resulting list of cited journals to identify core titles in the discipline, and five indexes were searched to assess coverage of these core titles. Results indicated that the cytotechnology journal literature had a small core but wide dispersion: one third of the 21,021 journal citations appeared in only 3 titles; another third appeared in an additional 26 titles; the remaining third were scattered in 1,069 different titles. Science Citation Index Expanded rated highest in indexing coverage of the core titles, followed by MEDLINE, EMBASE/Excerpta Medica, HealthSTAR, and Cumulative Index to Nursing and Allied Health Literature (CINAHL). The study's results also showed that journals were the predominantly cited format and that citing authors relied strongly on more recent literature. 相似文献

Objectives
This study describes the literature of hospital pharmacy and identifies the journals most commonly cited by authors in the field, the publication types most frequently cited, the age of citations, and the indexing access to core journals. The study also looks at differing citation practices between journals with a wide audience compared to a national journal with a focus on regional issues and trends in the field.Method
Cited references from five discipline-specific source journals were collected and analyzed for publication type and age. Two sets were created for comparison. Bradford''s Law of Scattering was applied to both sets to determine the most frequently cited journals.Results
Three-quarters of all cited items were published within the last 10 years (71%), and journal articles were the most heavily cited publication type (n=65,760, 87%). Citation analysis revealed 26 journal titles in Zone 1, 177 journal titles in Zone 2, and the remaining were scattered across 3,886 titles. Analysis of a national journal revealed Zone 1 comprised 9 titles. Comparison of the 2 sets revealed that Zone 1 titles overlapped, with the exception of 2 titles that were geographically focused in the national title.Conclusion
Hospital pharmacy literature draws heavily from its own discipline-specific sources but equally from core general and specialty medical journals. Indexing of cited journals is complete in PubMed and EMBASE but lacking in International Pharmaceutical Abstracts. Gray literature is a significant information source in the field. 相似文献16.
Titles are a crucial feature of research papers and have become increasingly important with changes in publishing practices and the explosion of published research. As a result, novice writers seeking to get their work noticed in international journals might benefit from a clear understanding of the features of research titles and an awareness of the relationship between language and disciplinary context. In this study, we explore this relationship and the impact of changing contexts on titles across the last 60 years on the length, form and content of 36,000 titles from the 10 leading journals from six disciplines spread along a soft-hard science continuum. Our results show a considerable increase in the length of titles coupled with more interrogative and compound titles in almost all disciplines. There has also been a growing mention of methods in the titles of hard knowledge papers with more frequent inclusion of results in the softer domains. These diachronic changes can be attributed to different characteristics of the fields and of the changing dynamics of the publishing context. Our findings have important implications for early career academics seeking to publish in English and contribute to studies of diachronic analysis of academic discourse. 相似文献

PURPOSE: The research sought to determine the impact of online journals on the use of print journals and interlibrary loan (ILL). SETTING: The Library of the Health Sciences-Peoria is a regional site of the University of Illinois at Chicago (UIC) Library with a print journal collection of approximately 400 titles. Since 1999, UIC site licenses have given students and faculty affiliated with UIC-Peoria access to more than 4,000 online full-text journal titles through the Internet. METHODOLOGY: The Library of the Health Sciences-Peoria has conducted a journal-use study over an extended period of time. The information collected from this study was used to assess the impact of 104 online journals, added to the collection in January 1999, on the use of print journals. RESULTS: Results of the statistical analysis showed print journal usage decreased significantly since the introduction of online journals (F(1,147) = 12.10, P < 0.001). This decrease occurred regardless of whether a journal was available only in print or both online and in print. Interlibrary loan requests have also significantly decreased since the introduction of online journals (F(2,30) = 4.46, P < 0.02). CONCLUSIONS: The decrease in use of the print collection suggests that many patrons prefer to access journals online. The negative impact the online journals have had on the use of the journal titles available only in print suggests users may be compromising quality for convenience when selecting journal articles. Possible implications for collection development are discussed. 相似文献

Occupational therapy, formally organized in the United States in 1917, is considered an allied health field. Mapping occupational therapy literature is part of a bibliometric project of the Medical Library Association's Nursing and Allied Health Resources Section's project for mapping the literature of allied health. Three core journals were selected from the years 1995 and 1996 and a determination was made of the extent to which the cited journal references were covered by standard indexing sources. Using Bradford's Law of Scattering three zones were created, each containing approximately one-third of the cited journal references. The results showed that three journals made up the first zone, 117 journals the second, and 657 the third. The most cited journal was the American Journal of Occupational Therapy. In the second zone, journals from twelve disciplines were identified. While MEDLINE provided the best overall indexing, the Cumulative Index to Nursing and Allied Health Literature (CINAHL) was the only database that indexed the three most cited journals plus nine of the currently active titles in occupational therapy. MEDLINE could improve its coverage of occupational therapy by indexing the journals of the British, Canadian, and Australian national associations. 相似文献
