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

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. 相似文献

Perfusionists select and operate the equipment necessary for monitoring, supporting, or temporarily replacing the patient's circulatory or respiratory function. There are over 3,000 perfusionists working in U.S. hospitals, medical and perfusionist groups, and as independent contractors. The purpose of this study was to identify the core literature of perfusion and to determine which major databases provide the most thorough access to this literature. This paper is part of the Medical Library Association Nursing and Allied Health Resource Section's project to map the literature of the allied health professions. It uses a bibliometric methodology to identify core journals. A group of forty-three journals was determined to make up the core journal literature of perfusion. MEDLINE provided the best overall indexing coverage for these journals, but librarians and perfusionists will wish to supplement its use with the Cumulative Index to Nursing and Allied Health Literature in order to access the journals written primarily for perfusionists. The study results can guide purchasing and database searching decisions of collection development and reference librarians, encourage the database producer to increase coverage of titles that are unindexed or underindexed, and advise perfusionists of the best access to their core literature. 相似文献

Objective:This study aims to identify the core journals cited in the health care management literature and to determine their coverage in the foremost bibliographic databases used by the discipline.Methods:Using the methodology outlined by the Medical Library Association''s Nursing and Allied Health Resource Section (NAHRS) protocol for “Mapping the Literature of Nursing and Allied Health Professions,” this study updates an earlier study published in 2007. Cited references from articles published in a three-year range (2016–2018) were collected from five health care management journals. Using Bradford''s Law of Scattering, cited journal titles were tabulated and ranked according to the number of times cited. Eleven databases were used to determine coverage of the most highly cited journal titles for all source journals, as well as for a subset of practitioner-oriented journals.Results:The most highly cited sources were journals, followed by government documents, Internet resources, books, and miscellaneous resources. The databases with the most complete coverage of Zone 1 and 2 were Scopus, Web of Science Core Collection, and PubMed, while the worst performing databases were Health Business Elite, ABI/Inform, and Business Source Complete.Conclusions:The literature of health care management has expanded rapidly in the last decade, with cumulative citations increasing by 76.6% and the number of cited journal titles increasing by nearly 70% since the original study. Coverage of the core journals in popular databases remains high, although specialized health care management and business databases did not perform as well as general or biomedical databases. 相似文献

Research on the literature of dietetics, apart from the broader field of nutrition, has not been reported in the literature. The purpose of this bibliometric study was to identify the core journals of dietetics and to determine the extent of indexing coverage for these journals. The study was conducted as part of a larger project, the Project for Mapping the Literature of Allied Health, sponsored by the Nursing and Allied Health Resources Section of the Medical Library Association. Citations appearing in three journals between 1995 and 1997 were analyzed by the methodology common to studies in the project. Results revealed that dietetic literature relies heavily on journal literature and on those journals that are from associated health sciences fields. Of the indexing services examined, EMBASE/Excerpta Medica and MEDLINE provided the most complete coverage of the literature. The study's findings have implications for those involved with the literature of dietetics. 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

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. 相似文献

Objectives:
The study updates Schloman''s 1997 study, “Mapping the Literature of Health Education.” The authors identify an updated list of core health education journals and determine the coverage of these journals by electronic indexes.Methods:
Citations from four source journals for the years 2006 to 2008 were analyzed using the established methodology of the “Mapping the Literature of Allied Health Project.” The cited journals were divided into three zones of productivity by using Bradford''s Law of Scattering.Results:
There were 19,907 citations in 602 source articles. Journal articles were the most commonly cited format type. Of the 1,896 journal titles cited, 20 (1.1%) made up the core journals. Together, the fields of medicine, health education, and psychology accounted for 85.0% of the journals in the core. Self-citation was found to be a common practice in the source journals. Scopus had the broadest journal coverage of the indexes examined.Conclusions:
The results of this study provide a new picture of the health education literature: The volume has grown significantly, cites older materials, and relies less on sexual health journals and more on psychology journals.Highlights
- Three of the four health education journals in this study showed a statistically significant increase in the number of journal articles published since 1993.
- The majority of core journals in the field are from medicine (35.0%), health education (30.0%), and psychology (20.0%), with the largest change in core journal make-up being an increase in psychology journals.
- Scopus provided the most thorough coverage of the cited journals, followed by MEDLINE, Social Sciences Citation Index, and CINAHL Plus with Full Text.
Implications
- Reference librarians should instruct users on more sophisticated ways to manage the growing volume of the health education literature.
- Collection development librarians may need to purchase and retain older materials to support health education research.
- Librarians should purchase and direct patrons to a variety of databases to completely cover the literature of medicine, health education, and psychology.

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11.

Objectives:
The purpose of this study was to identify (1) core journals in the literature of physical therapy, (2) currency of references cited in that literature, and (3) online databases providing the highest coverage rate of core journals.Method:
Data for each cited reference in each article of four source journals for three years were recorded, including type of literature, year of publication, and journal title. The journal titles were ranked in descending order according to the frequency of citations and divided into three zones using Bradford''s Law of Scattering. Four databases were analyzed for coverage rates of articles published in the Zone 1 and Zone 2 journals in 2007.Results:
Journal articles were the most frequently cited type of literature, with sixteen journals supplying one-third of the cited journal references. Physical Therapy was the most commonly cited title. There were more cited articles published from 2000 to 2007 than in any previous full decade. Of the databases analyzed, CINAHL provided the highest coverage rate for Zone 1 2007 publications.Conclusions:
Results were similar to a previous study, except for changes in the order of Zone 1 journals. Results can help physical therapists and librarians determine important journals in this discipline.Highlights
- More cited references were published in the last eight years studied than in any previous full decade.
- Physical Therapy, Archives of Physical Medicine and Rehabilitation (APMR), and Spine were the most frequently cited titles. Previous studies found APMR to be the most cited journal.
- CINAHL provided the highest coverage rate for the most commonly cited titles, with MEDLINE and EMBASE providing the best coverage for the next group of titles.
Implications
- Health sciences librarians and clinicians can use these results to identify important journals for developing collections and determining the need for access to back issues of journals.
- Multiple databases are needed for comprehensive coverage of the physical therapy discipline

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. 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

Objective:
This study examined citation patterns and indexing coverage from 2008 to 2010 to determine (1) the core literature of health care chaplaincy and (2) the resources providing optimum coverage for the literature.Methods:
Citations from three source journals (2008–2010 inclusive) were collected and analyzed according to the protocol created for the Mapping the Literature of Allied Health Professions Project. An analysis of indexing coverage by five databases was conducted. A secondary analysis of self-citations by source journals was also conducted.Results:
The 3 source journals—Chaplaincy Today, the Journal of Health Care Chaplaincy, and the Journal of Pastoral Care and Counseling—ranked as the top 3 journals in Zone 1 and provided the highest number of most frequently cited articles for health care chaplaincy. Additional journals that appeared in this highly productive zone covered the disciplines of medicine, psychology, nursing, and religion, which were also represented in the Zones 2 and 3 journals. None of the databases provided complete coverage for the core journals; however, MEDLINE provided the most comprehensive coverage for journals in Zones 1 and 2, followed by Academic Search Complete, CINAHL, PsycINFO, and ATLA. Self-citations for the source journals ranged from 9% to 16%.Conclusions:
Health care chaplaincy draws from a diverse body of inter-professional literature. Libraries wishing to provide access to journal literature to support health care chaplaincy at their institutions will be best able to do this by subscribing to databases and journals that cover medical, psychological, nursing, and religion- or spirituality-focused disciplines.Highlights
- Health care chaplaincy is a broadly inter-professional field that draws from and contributes to medical, nursing, psychological, and religion or spirituality literature.
- Two of the three source journals were sponsored by professional chaplaincy organizations.
- Journals and books were cited with almost equal frequency.
Implications
- For full coverage of the health care chaplaincy literature, librarians should consider searching in databases beyond MEDLINE, for example, CINAHL and Academic Search Complete, to assure comprehensive coverage.
- Health care chaplaincy researchers and educators considering publication will find the study useful for identifying relevant journals from related disciplines.

Objective:
The paper analyzes the journal evaluation criteria used to create the third edition of a core list of veterinary serials to determine the impact of each criterion on the final composition of the list in order to assess the value of using multiple criteria in creating a core list.Methods:
Three additional lists were generated from criteria that were previously combined to prepare the third edition of the “Basic List of Veterinary Medical Serials”: a list based on journal recommendations from veterinary specialty organizations, another list based on journals selected by veterinary librarians, and a list based on both indexing coverage and scholarly rank. The top fifteen journals in each of the three lists were then compared to reveal potential biases. Subject representation on the full lists generated by each of these methods was also compared.Results:
The list based on journal recommendations from veterinary specialty organizations exhibited a focus on clinically relevant titles. The list based on veterinary librarian recommendations resulted in the broadest subject coverage. The list based on indexing and scholarly rank, while emphasizing research titles, produced the largest number of unique titles.Conclusion:
A combination approach that includes objective evaluation measures and practical input, whether from librarians or discipline experts, can improve coverage and can result in a list that balances research-based with clinical practice journals.Highlights
- Analysis of criteria used to create the “Basic List of Veterinary Medical Serials” reveals biases inherent in different quality measures that result in different journal emphases.
- Use of indexing or scholarly rank is often thought of as a limiting factor, but in this study, the journals that were scored solely on these two criteria resulted in the inclusion of the greatest number of unique titles.
- Librarian input produced the broadest subject coverage of any list.
Implications
- An analysis of the strengths and weaknesses of various methodologies reveals clear evidence for using both objective and subjective criteria in developing a core list. Collection development decisions would equally benefit from this approach.
- Comparison of the top titles on core lists underscores the value of input from practitioners or discipline experts in collection decisions.
- Bias toward clinical content revealed in the input from the veterinary specialty organizations indicates the importance of understanding the purpose and compilation methods used in creating recommended lists before using them in collection development.

This article analyzes the bibliometric features (the number of pages, completion years, the fields of subject, the number of citations, and their distribution by types of sources and years) of 100 theses and dissertations completed at the Department of Librarianship of Hacettepe University between 1974 and 2002. Almost a quarter (24%) of all dissertations were on university libraries, followed by public libraries (9%). Doctoral dissertations were, on average, twice as long as master's theses and contained 2.5 times more citations. Monographs received more citations (50%) than journal articles did (42%). Recently completed theses and dissertations contained more citations to electronic publications. Fourteen (or 3.2% of all) journal titles (including Türk Kütüphaneciliği, College & Research Libraries, and Journal of the American Society for Information Science) received almost half (48.9%) of all citations. Eighty percent of journal titles were cited infrequently. No correlation was found between the frequency of citations of the most frequently cited journals and their impact factors. Cited journal titles in master's and doctoral theses and dissertations overlapped significantly. Similarly, journal titles cited in dissertations also overlapped significantly with those that were cited in the journal articles published in the professional literature. The distribution of citations to foreign journal titles fit Bradford's Law of Scattering. The mean half-life of all cited sources was 9 years. Sources cited in master's dissertations were relatively more current. Single authorship was the norm in cited resources. Coupled with in-library use data, findings of the present study can be used to identify the core journal titles in librarianship as well as to evaluate the existing library collections to decide which journal titles to keep, discard, or relegate to off-site storage areas. 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

Aim:The purpose of this study is to identify and describe the citing behavior of geomatics postgraduate students at the Wuhan University in China. These students constitute one of the main user groups of Wuhan University Library and the analysis of their use of literature (through the means of citation analysis) can yield valuable insights against which to benchmark and inform collection development policy and other services at the Information Technology Library (ITL) at Wuhan University.Design/methodology/approach:In this project, 9317 citations in 21 PhD and 180 MSc theses submitted at the Wuhan University in the years of 1988, 1996, and 2004 were analyzed. All cited materials were divided by output format (monographs, proceedings, journal articles) and the more in-depth analysis was conducted for all cited journals. The following characteristics of the cited journal literature were analyzed: subject, age, language, and dispersion of journal titles.Findings:An increased use of journal literature in bibliographies of geomatics theses was observed over time. A trend to increase citations to international conference proceedings was also noted as well as a trend to cite more journals in disciplines other than surveying and mapping. It was also noted that, over time, citations to documents in languages other than Chinese and English have significantly decreased (in some cases, disappeared). Large dispersion among the most frequently cited journals in different time periods (only 25% of titles were repeated in 1988, 1996, and 2004 top ranking journal lists) was also noted. It was also noted that the core of geomatics literature is expanding (it now takes 42% of journal titles to cover 80% of all citations).Practical implications:By analyzing citation patterns of the graduate students of geomatics in China, we can track the developments and changes within that discipline in China and can compare these trends internationally (e.g. increased role of a journal, the importance of conference proceedings, domination of the English-language sources, dispersion of journal literature, and increasing multidisciplinarity of the discipline). The techniques and methods used in this study can be replicated to study other disciplines. Also, it is hoped that the findings of this research will inform collection development planning, development of reference services, and information literacy training. 相似文献

The goal of this analysis was to obtain local citation behavior data on undergraduates researching history, political science, and sociology papers. The study found that students cited books and journals even with the availability of web sources; however, usage varied by subject. References to specific websites' domains also varied across subject area. Most of the top journal titles that students referenced were online and locally owned. Students cited a broader range of journal titles than predicted by the Law of Scattering and cited titles across a wide array of subject areas. This data helped identify potential gaps in the library's collection and services. 相似文献
