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

Objectives:
The research identified the publication types and ages most frequently cited in the infectious diseases literature and the most commonly cited journals.Methods:
From 2008–2010, 5,056 articles in 5 infectious diseases journals cited 166,650 items. Two random samples were drawn: one (n = 1,060) from the total set of citations and one (n = 1,060) from the citations to journal articles. For each sample citation, publication type and date, age of cited item, and inclusion of uniform resource locator (URL) were collected. For each item in the cited journal articles sample, journal title, publication date, and age of the cited article were collected. Bradford zones were used for further analysis.Results:
Journal articles (91%, n = 963) made up the bulk of cited items, followed by miscellaneous items (4.6%, n = 49). Dates of publication for cited items ranged from 1933–2010 (mean = 2001, mode = 2007). Over half (50.2%, n = 483) of cited journal articles were published within the previous 5 years. The journal article citations included 358 unique journal titles.Discussion:
The citations to current and older publications in a range of disciplines, heavy citation of journals, and citation of miscellaneous and government documents revealed the depth and breadth of resources needed for the study of infectious diseases.Highlights
- Literature on infectious diseases is multidisciplinary, encompassing medical specialties, public health, and the medical sciences.
- Infectious disease publications cite journal articles more than 90% of the time. Cited journal articles greatly range in age at citation: more than a quarter were over 10 years old.
- Infectious disease citation patterns resemble clinical medicine citation patterns more than public health citation patterns.
Implications
- Infectious disease professionals need access to general medicine titles as well as infectious disease, immunology, virology, microbiology, and public health literature.
- Librarians serving infectious disease researchers and practitioners should provide access to older materials, especially journal back files, to support the cyclical needs of their patrons.

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.

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.

Objective
The researchers assessed prevalence in the clinical case report literature of multiple reports independently reporting the same (or nearly the same) main finding.Methods
Results from forty-five PubMed queries were examined for incidence and features of main findings (“nuggets”) shared in at least four case reports.Results
The authors found that nuggets are surprisingly prevalent and large in the case report literature, the largest found so far was reported in seventeen articles. In most cases, the main findings of case reports were evident from examining titles alone.Conclusions
Our curated examples should serve as gold standards for developing specific automated methods for finding nuggets. Nuggets potentially enable finding-based (instead of topic-based) information retrieval. 相似文献8.
Objective: The research analyzes usage of a major biomedical library''s pre-1993 print journal collection.Methodology: In July 2003, in preparation for a renovation and expansion project, the Biomedical Library at the University of California, San Diego, moved all of its pre-1993 journal volumes off-site, with the exception of twenty-two heavily used titles. Patrons wishing to consult one of these stored volumes could request that it be delivered to the library for their use. In the spring of 2006, an analysis was made of these requests.Results: By July of 2006, 79,827 journal volumes published in 1992 or earlier had been requested from storage. The number of requests received declined with age of publication. The usage distribution exhibited a “long tail”: 50% of the 79,827 requests were for journal volumes published before 1986. The availability of electronic access dramatically reduced the chance that corresponding print journal volumes would be requested.Conclusions: The older biomedical print journal literature appears to be of continued value to the biomedical research community. When electronic access was provided to the older literature, demand for older print volumes declined dramatically.
Highlights
- Analysis of requests for stored biomedical journal volumes published prior to 1993 indicates that older biomedical journal literature receives substantial use: during this 3-year study, there were nearly 80,000 requests for journal volumes published in 1992 or earlier, with half the requests for volumes published from 1986–1992 and 40% of the request for volumes published from 1970–1985. These results indicate that retaining older print volumes, or providing easy access to the older literature through electronic journals or other means, will likely be required to meet user information needs.
- Use of older journal volumes varies by title and by user population, and a small number of journal titles were responsible for most of the use.
- Requests for older print biomedical journal titles dropped significantly when electronic access became available.
Implications
- Biomedical libraries should carefully consider implications of eliminating on-site access to older journal literature for users and budgets.
- Removing access to older journal literature may result in higher demand for interlibrary loan and document delivery services.
- Biomedical libraries can safely substitute reliable electronic access to older literature to meet ongoing needs for this information, thereby creating space for other purposes.

Objective:
This paper presents the methods and results of a study designed to produce the third edition of the “Basic List of Veterinary Medical Serials,” which was established by the Veterinary Medical Libraries Section in 1976 and last updated in 1986.Methods:
A set of 238 titles were evaluated using a decision matrix in order to systematically assign points for both objective and subjective criteria and determine an overall score for each journal. Criteria included: coverage in four major indexes, scholarly impact rank as tracked in two sources, identification as a recommended journal in preparing for specialty board examinations, and a veterinary librarian survey rating.Results:
Of the 238 titles considered, a minimum scoring threshold determined the 123 (52%) journals that constituted the final list. The 36 subject categories represented on the list include general and specialty disciplines in veterinary medicine. A ranked list of journals and a list by subject category were produced.Conclusion:
Serials appearing on the third edition of the “Basic List of Veterinary Medical Serials” met expanded objective measures of quality and impact as well as subjective perceptions of value by both librarians and veterinary practitioners.Highlights
- The 123 journals on the “Basic List of Veterinary Medical Serials” include 117 journals with a decision matrix score of 15 points or higher, with an additional 6 journals included for more complete subject representation.
- Subject categories with the greatest number of journals are internal medicine, food animal medicine, and research.
- Updates for the third edition of the “Basic List” include 59 new titles and 13 new subject categories.
Implications
- The third edition of the “Basic List” provides a useful collection development and assessment tool for veterinary libraries, as well as general libraries with a need to develop a core collection of veterinary resources.
- The decision matrix approach, using standard quantitative and focused qualitative measures, provides a useful methodology for creating core lists in other disciplines.

Objective
The choice of bibliographic database during the systematic review search process has been an ongoing conversation among information specialists. With newer information sources, such as Google Scholar and clinical trials registries, we were interested in which databases were utilized by information specialists and systematic review researchers.Method
We retrieved 144 systematic reviews and meta-analyses from 4 clinical endocrinology journals and extracted all information sources used during the search processes.Results
Findings indicate that traditional bibliographic databases are most often used, followed by regional databases, clinical trials registries, and gray literature databases.Conclusions
This study informs information specialists about additional resources that may be considered during the search process. 相似文献11.

Objective
References from drug-related Wikipedia articles and a drug information database were compared.Methods
Drugs in Food and Drug Administration (FDA) MedWatch alerts from January–July 2013 were searched in Wikipedia and Lexicomp to compare reference types and to assess the time for drug safety information to be incorporated into Wikipedia articles.Results
Wikipedia most commonly cited peer-reviewed journal articles (49.2%) and news articles (12.0%). MedWatch citations were incorporated into Wikipedia on average in 5.9 days.Conclusions
Wikipedia cited various sources but may not be a reliable, up-to-date resource for drug safety information. 相似文献12.

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

Question
What to do when a major database ceases publication?Setting
An urban, academic health sciences library with four campuses serves a university health sciences system, a college of medicine, and five other health sciences colleges.Methods
Usage statistics of each e-book title in the resource were carefully analyzed. Purchase decisions were made based on the assessment of usage.Results
Sustainable resources were acquired from other vendors, with perpetual access for library users.Conclusion
This systematic process of finding alternative resources is an example of librarians'' persistence in acquiring perpetual electronic resources when a major resource is cancelled. 相似文献15.

Objective
This study investigated responsibilities, skill sets, degrees, and certifications required of health care navigators in order to identify areas of potential overlap with health sciences librarianship.Method
The authors conducted a content analysis of health care navigator position announcements and developed and assigned forty-eight category terms to represent the sample''s responsibilities and skill sets.Results
Coordination of patient care and a bachelor''s degree were the most common responsibility and degree requirements, respectively. Results also suggest that managing and providing health information resources is an area of overlap between health care navigators and health sciences librarians, and that librarians are well suited to serve on navigation teams.Conclusion
Such overlap may provide an avenue for collaboration between navigators and health sciences librarians. 相似文献16.

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

Objectives:
This study sought to ascertain the publication rate of abstracts presented at the annual meetings of the Medical Library Association (MLA) for the years of 2002 and 2003. The secondary objectives were to examine possible reasons for non-publication and factors influencing publication.Methods:
A total of 442 abstracts from both meeting years, consisting of presented papers and posters, were examined. The 2 methods used to obtain a publication rate were literature searches and an online questionnaire sent to first authors. The questionnaire also asked abstract authors about reasons for non-publication and other factors that might have influenced their decisions about whether or not to submit the project for publication.Results:
The overall publication rate from the survey was 26.5%, and the publication rate found via literature searching was 27.6%. The most common reason given for non-publication was time restrictions. Also notable was the large proportion of abstracts written by librarians working at universities and those having 25 or more years in the library profession.Discussion:
Publication rates for abstracts presented at the Medical Library Association meetings for the years studied rank at the low end in comparison with other medical professional associations. Further research into factors affecting publication may reveal ways to increase this rate.Highlights
- Publication rates from posters and presentations at the Medical Library Association''s 2002 and 2003 annual meetings were estimated at less than 28.0% using data from an author survey and literature search. In contrast, a Cochrane systematic review of 79 similar biomedical research studies found a mean publication rate of 44.5%.
- Respondents listed time restrictions as their primary reason for not submitting their presentations for publication.
Implications
- Compared to biomedical conferences, relatively little of the information presented at Medical Library Association annual meetings is available as peer-reviewed evidence in the published literature.
- Each profession has different norms for the nature and style of information in presentations at meetings. The further presenters get from basic research, the more difficult it may be for them to conceptualize a presentation as a formal paper. Diverse publication rates between professions are likely to remain.
- Additional study could be aimed at further clarifying the reasons for non-publication and possible means to ameliorate them.
