1.  Bibliometric Analysis of the Korean Journal of Parasitology: Measured from SCI, PubMed, Scopus, and Synapse Databases 
The Korean Journal of Parasitology  2009;47(Suppl):S155-S167.
The Korean Journal of Parasitology (KJP) is the official journal of the Korean Society for Parasitology which is celebrating its 50th anniversary in 2009. To assess the contributions and achievements of the KJP, bibliometric analysis was conducted based on the citation data retrieved from 4 major databases; SCI, PubMed, Synapse, and Scopus. It was found that the KJP articles were constantly cited by the articles published in major international journals represented in these databases. More than 60% of 1,370 articles published in the KJP from 1963 to June 2009 were cited at least once by SCI articles. The overall average times cited by SCI articles are 2.6. The rate is almost 3 times higher for the articles published in the last 10 years compared to 1.0 for the articles of the 1960s. The SCI journal impact factor for 2008 is calculated as 0.871. It is increasing and it is expected to increase further with the introduction of the KJP in the database in 2008. The more realistic h-indixes were measured from the study data set covering all the citations to the KJP; 17 for SCI, 6 for PubMed, 19 for Synapse, and 17 for Scopus. Synapse extensively picked up the citations to the earlier papers not retrievable from the other 3 databases. It identified many papers published in the 1960s and in the 1980s which have been cited heavily, proving the central role of the KJP in the dissemination of the important research findings over the last 5 decades.

The aim of the paper is to overview the leading information processing domain in Russia and Eastern Europe, namely All Russian Institute for Scientific and Technical Information (VINITI ) of the Russian Academy of Sciences. Russian science structure is different from that in the Western Europe and the US. The main aim of VINITI is to collect, process and disseminate scientific information on various fields of science and technology, published in 70 countries in 40 languages, selected from books, journals, conference proceedings, and patents. A special attention is given to the journal selection and depositing manuscripts (a kind of grey literature), an important source for Russian research. VINITI has created the largest database containing about 30 million records dating back to 1980. About 80,000-100,000 new records are added monthly. VINITI publishes the Journal Abstract (JA) on 19 fields of science, including medicine, containing about a million publications annually. Two thirds of these records are foreign and 36.7% – Russian sources.

3.  The influence of Iranian scientific journals in disseminating medical information 
Scientific journals are the most credible and updated information resources for valid information in the various fields of science and technology. The present study investigates the status of Iranian scientific journals in disseminating medical information to the world of science.
Materials and Methods:
Total 163 Iranian medical journals accredited by national medical journals commission of Iranian ministry of health and medical education were evaluated through a cross-sectional study. The results were represented in descriptive statistics in the form of table and chart.
The study showed that 89.6% of Iranian medical journals were covered by regional information databases. Web of Science database indexed 22 (13.5%) Iranian journals in the field of medical science. Only six (6.7%) journals were indexed by Medline. Fifty-eight (35.6%) journals were in English, 102 (62.6%) in Persian, and three (1.8%) were bilingual which published their articles both in Persian and English languages. The highest Impact factor belonged to Iranian Journal of Allergy Asthma and Immunology.
Improving scientific credibility of Iranian scholarly journals and their influence in disseminating medical information calls for a precise scientific and executive administration in publishing standards and also in the quality of content.

5.  Some citation-related characteristics of scientific journals published in individual countries 
Scientometrics  2013;97:719-741.
Relationships between publication language, impact factors and self-citations of journals published in individual countries, eight from Europe and one from South America (Brazil), are analyzed using bibliometric data from Thomson Reuters JCR Science Edition databases of ISI Web of Knowledge. It was found that: (1) English-language journals, as a rule, have higher impact factors than non-English-language journals, (2) all countries investigated in this study have journals with very high self-citations but the proportion of journals with high self-citations with reference to the total number of journals published in different countries varies enormously, (3) there are relatively high percentages of low self-citations in high subject-category journals published in English as well as non-English journals but national-language journals have higher self-citations than English-language journals, and (4) irrespective of the publication language, journals devoted to very specialized scientific disciplines, such as electrical and electronic engineering, metallurgy, environmental engineering, surgery, general and internal medicine, pharmacology and pharmacy, gynecology, entomology and multidisciplinary engineering, have high self-citations.

Indian Journal of Psychiatry  2000;42(2):203-208.
A previous study found that many papers in the Indian Journal of Psychiatry (UP) had failed to reference relevant papers previously published in the same journal. The present study examined whether any change in referencing patterns had occurred The database comprised 182 eligible articles published in the UP during 1993-1996. In general, few articles cited previous UP papers (median citations, 0-1); however, few articles omitted to cite previous (relevant) UP research (median omissions, 0-1). The average number of articles cited: omitted was 2:1. Original articles cited as well as omitted more UP references than brief communications. The larger the number of total references cited, the larger was the number of UP references both cited and omitted. No significant changes in referencing patterns was evident across the years. Indexing of articles, an important method of identifying relevant, previously published research was grossly adequate in 89% of articles; the average article received 2 index entries. While UP papers appear to be receiving greater attention, it is suggested that room for improvement remains.

7.  Medline-based bibliometric analysis of gastroenterology journals between 2001 and 2007 
AIM: To analyze the MEDLINE-indexed publications in gastroenterology specialty journals from 2001 to 2007. Special attention was paid to specific types of articles, the number of publications for individual authors and the author count in each journal.
METHODS: The bibliographic entries of papers belonging to journals listed under the subject heading of “gastroenterology” were downloaded from MEDLINE on the PubMed web site. The analysis was limited to journal articles published between January 1, 2001 and December 31, 2007. The analytical dimensions of an article included journal, publication year, publication type, and author name (the last name and initials).
RESULTS: According to MEDLINE, 81 561 articles were published in 91 gastroenterology journals from 2001 to 2007. The number of articles increased from 9447 in 2001 to 13 340 in 2007. Only 12 journals had more than 2000 articles indexed in MEDLINE. The “World Journal of Gastroenterology” had the largest number of publications (5684 articles), followed by “Hepato-Gastroenterology” (3036) and “Gastrointestinal Endoscopy” (3005). Of all the articles published, reviews accounted for 17.2% and case reports for 15.4%. Only 3739 randomized controlled trials (4.6% of all articles) were published and their annual number increased from 442 in 2001 to 572 in 2007. Among 141 741 author names appearing in the articles of gastroenterology journals, 92 429 had published only in one journal, 22 585 in two journals, 9996 in three journals, and 16 731 in more than three journals. The “World Journal of Gastroenterology” had the greatest number of authors (17 838), followed by “Gastroenterology” (12 770), “Digestive Diseases and Sciences” (11 395), “American Journal of Gastroenterology” (10 889), and “Hepatology” (10 588).
CONCLUSION: Global gastroenterology publications displayed a continuous growth in the new millennium. The change was most striking in certain journals. Regular bibliometric analyses on the trends and specific topics would help researchers publish more efficiently and allow editors to adjust the policy more accurately.

8.  Knowledge Economy Core Journals: Identification through LISTA Database Analysis 
Acta Informatica Medica  2013;21(1):60-62.
Knowledge economy has become increasingly broad over the years and identification of core journals in this field can be useful for librarians in journal selection process and also for researchers to select their studies and finding Appropriate Journal for publishing their articles. Present research attempts to determine core journals of Knowledge Economy indexed in LISTA (Library and Information Science and Technology).
The research method was bibliometric and research population include the journals indexed in LISTA (From the start until the beginning of 2011) with at least one article a bout “knowledge economy”. For data collection, keywords about “knowledge economy”–were extracted from the literature in this area–have searched in LISTA by using title, keyword and abstract fields and also taking advantage of LISTA thesaurus. By using this search strategy, 1608 articles from 390 journals were retrieved. The retrieved records import in to the excel sheet and after that the journals were grouped and the Bradford’s coefficient was measured for each group. Finally the average of the Bradford’s coefficients were calculated and core journals with subject area of “Knowledge economy” were determined by using Bradford’s formula.
By using Bradford’s scattering law, 15 journals with the highest publication rates were identified as “Knowledge economy” core journals indexed in LISTA. In this list “Library and Information update” with 64 articles was at the top. “ASLIB Proceedings” and “Serials” with 51 and 40 articles are next in rank. Also 41 journals were identified as beyond core that “Library Hi Tech” with 20 articles was at the top.
Increased importance of knowledge economy has led to growth of production of articles in this subject area. So the evaluation of journals for ranking these journals becomes a very challenging task for librarians and generating core journal list can provide a useful tool for journal selection and also quick and easy access to information. Core journal list and beyond core journal list obtained from this study can be used by librarians and researchers in this field.

9.  The rate of growth in scientific publication and the decline in coverage provided by Science Citation Index 
Scientometrics  2010;84(3):575-603.
The growth rate of scientific publication has been studied from 1907 to 2007 using available data from a number of literature databases, including Science Citation Index (SCI) and Social Sciences Citation Index (SSCI). Traditional scientific publishing, that is publication in peer-reviewed journals, is still increasing although there are big differences between fields. There are no indications that the growth rate has decreased in the last 50 years. At the same time publication using new channels, for example conference proceedings, open archives and home pages, is growing fast. The growth rate for SCI up to 2007 is smaller than for comparable databases. This means that SCI was covering a decreasing part of the traditional scientific literature. There are also clear indications that the coverage by SCI is especially low in some of the scientific areas with the highest growth rate, including computer science and engineering sciences. The role of conference proceedings, open access archives and publications published on the net is increasing, especially in scientific fields with high growth rates, but this has only partially been reflected in the databases. The new publication channels challenge the use of the big databases in measurements of scientific productivity or output and of the growth rate of science. Because of the declining coverage and this challenge it is problematic that SCI has been used and is used as the dominant source for science indicators based on publication and citation numbers. The limited data available for social sciences show that the growth rate in SSCI was remarkably low and indicate that the coverage by SSCI was declining over time. National Science Indicators from Thomson Reuters is based solely on SCI, SSCI and Arts and Humanities Citation Index (AHCI). Therefore the declining coverage of the citation databases problematizes the use of this source.

10.  Citation Analysis of the Korean Journal of Urology From Web of Science, Scopus, Korean Medical Citation Index, KoreaMed Synapse, and Google Scholar 
Korean Journal of Urology  2013;54(4):220-228.
The Korean Journal of Urology began to be published exclusively in English in 2010 and is indexed in PubMed Central/PubMed. This study analyzed a variety of citation indicators of the Korean Journal of Urology before and after 2010 to clarify the present position of the journal among the urology category journals. The impact factor, SCImago Journal Rank (SJR), impact index, Z-impact factor (ZIF, impact factor excluding self-citation), and Hirsch Index (H-index) were referenced or calculated from Web of Science, Scopus, SCImago Journal & Country Ranking, Korean Medical Citation Index (KoMCI), KoreaMed Synapse, and Google Scholar. Both the impact factor and the total citations rose rapidly beginning in 2011. The 2012 impact factor corresponded to the upper 84.9% in the nephrology-urology category, whereas the 2011 SJR was in the upper 58.5%. The ZIF in KoMCI was one fifth of the impact factor because there are only two other urology journals in KoMCI. Up to 2009, more than half of the citations in the Web of Science were from Korean researchers, but from 2010 to 2012, more than 85% of the citations were from international researchers. The H-indexes from Web of Science, Scopus, KoMCI, KoreaMed Synapse, and Google Scholar were 8, 10, 12, 9, and 18, respectively. The strategy of the language change in 2010 was successful from the perspective of citation indicators. The values of the citation indicators will continue to increase rapidly and consistently as the research achievement of authors of the Korean Journal of Urology increases.

11.  How to Search, Write, Prepare and Publish the Scientific Papers in the Biomedical Journals 
Acta Informatica Medica  2011;19(2):68-79.
This article describes the methodology of preparation, writing and publishing scientific papers in biomedical journals. given is a concise overview of the concept and structure of the System of biomedical scientific and technical information and the way of biomedical literature retreival from worldwide biomedical databases. Described are the scientific and professional medical journals that are currently published in Bosnia and Herzegovina. Also, given is the comparative review on the number and structure of papers published in indexed journals in Bosnia and Herzegovina, which are listed in the Medline database.
Analyzed are three B&H journals indexed in MEDLINE database: Medical Archives (Medicinski Arhiv), Bosnian Journal of Basic Medical Sciences and Medical Gazette (Medicinki Glasnik) in 2010. The largest number of original papers was published in the Medical Archives. There is a statistically significant difference in the number of papers published by local authors in relation to international journals in favor of the Medical Archives. True, the Journal Bosnian Journal of Basic Medical Sciences does not categorize the articles and we could not make comparisons. Journal Medical Archives and Bosnian Journal of Basic Medical Sciences by percentage published the largest number of articles by authors from Sarajevo and Tuzla, the two oldest and largest university medical centers in Bosnia and Herzegovina. The author believes that it is necessary to make qualitative changes in the reception and reviewing of papers for publication in biomedical journals published in Bosnia and Herzegovina which should be the responsibility of the separate scientific authority/ committee composed of experts in the field of medicine at the state level.

Most of medical journals now has it’s electronic version, available over public networks. Although there are parallel printed and electronic versions, and one other form need not to be simultaneously published. Electronic version of a journal can be published a few weeks before the printed form and must not has identical content. Electronic form of a journals may have an extension that does not contain a printed form, such as animation, 3D display, etc., or may have available fulltext, mostly in PDF or XML format, or just the contents or a summary. Access to a full text is usually not free and can be achieved only if the institution (library or host) enters into an agreement on access. Many medical journals, however, provide free access for some articles, or after a certain time (after 6 months or a year) to complete content. The search for such journals provide the network archive as High Wire Press, Free Medical It is necessary to allocate PubMed and PubMed Central, the first public digital archives unlimited collect journals of available medical literature, which operates in the system of the National Library of Medicine in Bethesda (USA). There are so called on- line medical journals published only in electronic form. It could be searched over on-line databases. In this paper authors shortly described about 30 data bases and short instructions how to make access and search the published papers in indexed medical journals.

13.  Mapping the core journals of the physical therapy literature* 
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.
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.
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.
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.

14.  Measuring use patterns of online journals and databases 
Purpose: This research sought to determine use of online biomedical journals and databases and to assess current user characteristics associated with the use of online resources in an academic health sciences center.
Setting: The Library of the Health Sciences–Peoria is a regional site of the University of Illinois at Chicago (UIC) Library with 350 print journals, more than 4,000 online journals, and multiple online databases.
Methodology: A survey was designed to assess online journal use, print journal use, database use, computer literacy levels, and other library user characteristics. A survey was sent through campus mail to all (471) UIC Peoria faculty, residents, and students.
Results: Forty-one percent (188) of the surveys were returned. Ninety-eight percent of the students, faculty, and residents reported having convenient access to a computer connected to the Internet. While 53% of the users indicated they searched MEDLINE at least once a week, other databases showed much lower usage. Overall, 71% of respondents indicated a preference for online over print journals when possible.
Conclusions: Users prefer online resources to print, and many choose to access these online resources remotely. Convenience and full-text availability appear to play roles in selecting online resources. The findings of this study suggest that databases without links to full text and online journal collections without links from bibliographic databases will have lower use. These findings have implications for collection development, promotion of library resources, and end-user training.

15.  Mapping the literature of speech-language pathology. 
The purpose of this study, part of the Medical Library Association (MLA) Nursing and Allied Health Resources Section's project to map the allied health literature, is to identify the core journals in the field of speech-language pathology and to identify indexing and abstracting services that provide access to these journals. Four representative speech-language pathology journals were selected and subjected to citation analysis to determine which journals were cited and how many times each was cited. Bradford's Law of Scattering was applied to the resulting list of journals to identify the core journals of this discipline. Six indexing and abstracting services were selected and scanned to determine coverage for the speech-language pathology core journals. The core journals received broad coverage in the health sciences and social sciences indexing and abstracting databases surveyed, although there was no one database that provided complete coverage of all core journals. The full Current Contents database provides the most extensive coverage of core journals. For individuals without access to the complete Current Contents database, a combined search of both MEDLINE and PsycINFO provides very comprehensive coverage of core journals.

16.  Visibility of medical informatics regarding bibliometric indices and databases 
The quantitative study of the publication output (bibliometrics) deeply influences how scientific work is perceived (bibliometric visibility). Recently, new bibliometric indices and databases have been established, which may change the visibility of disciplines, institutions and individuals. This study examines the effects of the new indices on the visibility of Medical Informatics.
By objective criteria, three sets of journals are chosen, two representing Medical Informatics and a third addressing Internal Medicine as a benchmark. The availability of index data (index coverage) and the aggregate scores of these corpora are compared for journal-related (Journal impact factor, Eigenfactor metrics, SCImago journal rank) and author-related indices (Hirsch-index, Egghes G-index). Correlation analysis compares the dependence of author-related indices.
The bibliometric visibility depended on the research focus and the citation database: Scopus covers more journals relevant for Medical Informatics than ISI/Thomson Reuters. Journals focused on Medical Informatics' methodology were negatively affected by the Eigenfactor metrics, while the visibility profited from an interdisciplinary research focus. The correlation between Hirsch-indices computed on citation databases and the Internet was strong.
The visibility of smaller technology-oriented disciplines like Medical Informatics is changed by the new bibliometric indices and databases possibly leading to suitably changed publication strategies. Freely accessible author-related indices enable an easy and adequate individual assessment.

17.  How Far Has the International Neurourology Journal Progressed Since Its Transformation Into an English Language Journal? 
The publisher of the International Neurourology Journal changed the text to English in 2010 to promote the journal as an international publication. Four years later, what has happened to this journal? This paper will use citation indicators to describe the degree of internationalization.
Citation indicators such as impact factors, total citations from Web of Science, Science Journal Rankings (SJR), cites per documents (2 years), and Hirsch indexes (h-indexes) from Web of Science, digital object identifier (DOI)/CrossRef, ScimagoJR, or Scopus were calculated. In addition, the native countries of the authors and researchers citing the journal in Web of Science were analyzed.
Impact factors in 2012 and 2013 were 0.645 and 0.857, respectively. Total citations in 2011, 2012, and 2013 from Web of Science were 15, 51, and 99, respectively, and the SJRs in 2011 and 2012 were 0.220 and 0.390, respectively. The h-indexes from DOI/CrossRef, Scopus, and Web of Science were 7, 8, and 6, respectively. Out of 153 unsolicited published papers, 27 (17.6%) were from outside of Korea. The researchers citing the journal in Web of Science and Scopus were primarily from the United States, Korea, China, the United Kingdom, and France. Funding agencies supported 39 of 101 original articles (38.6%).
After changing the text to the English language, the citation indicators show that the International Neurourology Journal has been elevated to an international journal. Although the nationality of authors varies from year to year, the increase in the number of manuscripts from international authors is obvious.

18.  Science production in Iran: The scenario of Iranian medical journals 
In Iran, the number of published articles has increased significantly in the basic and applied sciences including medicine and its subspecialties during the recent years. The present study reviewed Iranian science production in medicine, focusing on Iranian medical journals and assessing the current status of Iranian medical journals in several information databases. The study revealed that only a few number of Iranian biomedical journals were indexed by Web of Science, Medline, Scopus and Biological abstract, but most of them have been covered by Index Copernicus and Index Medicus for Eastern Mediterranean Region. Observing some important factors such as journal's basic publishing standards may increase the number of Iranian medical journals indexed by reputable information databases and improve Iranian contribution to the world science.

19.  ScienceCentral: open access full-text archive of scientific journals based on Journal Article Tag Suite regardless of their languages 
Biochemia Medica  2013;23(3):235-236.
ScienceCentral, a free or open access, full-text archive of scientific journal literature at the Korean Federation of Science and Technology Societies, was under test in September 2013. Since it is a Journal Article Tag Suite-based full text database, extensible markup language files of all languages can be presented, according to Unicode Transformation Format 8-bit encoding. It is comparable to PubMed Central: however, there are two distinct differences. First, its scope comprises all science fields; second, it accepts all language journals. Launching ScienceCentral is the first step for free access or open access academic scientific journals of all languages to leap to the world, including scientific journals from Croatia.

20.  Where should the pharmacy researcher look first? Comparing International Pharmaceutical Abstracts and MEDLINE. 
This study compared the usefulness of various CD-ROM versions of International Pharmaceutical Abstracts (IPA) and MEDLINE for pharmacy research. Journal coverage as well as the strengths and weaknesses of database structure and contents were considered. The journals indexed in each database were compared to those identified in a survey of the research journals most important to University of Maryland at Baltimore pharmacy faculty and in a similar North Carolina study rating pharmacy journals. In addition, indexed journals were checked against the Institute for Scientific Information's most recent list of high-impact journals in pharmacology and pharmacy. Searches representing a variety of topics relevant to pharmacy were conducted in both databases, and the number and relevance of citations located were analyzed. Results showed that IPA indexed a greater number of pharmacy titles, but that MEDLINE indexed more pharmacy journals designated in studies as significant to the field. There was little overlap in coverage between the two databases. MEDLINE produced larger retrievals for the majority of questions, but many citations retrieved in IPA did not appear in MEDLINE.

21.  Medical papers related to keywords of vaccine and vaccination in KoreaMed database, Korea (1962-2012) 
To describe the present status and changing patterns of medical papers related to keywords of vaccine and vaccination published in Korea over the last 50 years, and provide basic data for future studies.
Materials and Methods
185,603 papers are registered in the medical database KoreaMed, which is run by Korean Association of Medical Journal Editors. Among these papers, a search with the keywords vaccine or vaccination revealed a total of 1,089 articles which were published on vaccine and/or vaccination during the period of September 2, 1962 to April 30, 2012. Our study endeavors to analyze these 1,089 articles.
Only one article published with the keywords vaccine and/or vaccination was published in the 1960s, and the number of journals steadily increased starting from the 1970s (24 articles) to 2 times, 10 times, 20 times in the 1980s, 1990s, and the 2000s (585 articles), respectively. The articles were classified into reviews (20.2%), original articles with clinical study (40.7%), original articles with experimental study (24.6%), and case reports (8.2%). The review articles mainly dealt with an overview. The original articles with clinical study were on epidemiology, effect and immunogenicity, clinical trial. Original articles with experimental study were mainly comprised of complication and overview. Articles on vaccine, pathogen or disease topics were mostly microorganisms such as bacteria or viruses, and studies on anti-cancer vaccines or vaccines of specific diseases were sparse.
The above data reflects the clinical uses of vaccines in Korea and the history of vaccine studies. The number of vaccine-related articles is increasing rapidly since the first article was published in 1962. This implies that with the increase of studies of clinical trials, clinical uses and results and analyses of the results, articles relating to basic studies are also on the rise. We intend these findings to be of use to researchers in this active and expanding field.

22.  Assessing availability of scientific journals, databases, and health library services in Canadian health ministries: a cross-sectional study 
Evidence-informed health policymaking logically depends on timely access to research evidence. To our knowledge, despite the substantial political and societal pressure to enhance the use of the best available research evidence in public health policy and program decision making, there is no study addressing availability of peer-reviewed research in Canadian health ministries.
To assess availability of (1) a purposive sample of high-ranking scientific journals, (2) bibliographic databases, and (3) health library services in the fourteen Canadian health ministries.
From May to October 2011, we conducted a cross-sectional survey among librarians employed by Canadian health ministries to collect information relative to availability of scientific journals, bibliographic databases, and health library services. Availability of scientific journals in each ministry was determined using a sample of 48 journals selected from the 2009 Journal Citation Reports (Sciences and Social Sciences Editions). Selection criteria were: relevance for health policy based on scope note information about subject categories and journal popularity based on impact factors.
We found that the majority of Canadian health ministries did not have subscription access to key journals and relied heavily on interlibrary loans. Overall, based on a sample of high-ranking scientific journals, availability of journals through interlibrary loans, online and print-only subscriptions was estimated at 63%, 28% and 3%, respectively. Health Canada had a 2.3-fold higher number of journal subscriptions than that of the provincial ministries’ average. Most of the organisations provided access to numerous discipline-specific and multidisciplinary databases. Many organisations provided access to the library resources described through library partnerships or consortia. No professionally led health library environment was found in four out of fourteen Canadian health ministries (i.e. Manitoba Health, Northwest Territories Department of Health and Social Services, Nunavut Department of Health and Social Services and Yukon Department of Health and Social Services).
There is inequity in availability of peer-reviewed research in the fourteen Canadian health ministries. This inequity could present a problem, as each province and territory is responsible for formulating and implementing evidence-informed health policies and services for the benefit of its population.

23.  Using text mining to link journal articles to neuroanatomical databases 
The Journal of comparative neurology  2012;520(8):10.1002/cne.23012.
The electronic linking of neuroscience information, including data embedded in the primary literature, would permit powerful queries and analyses driven by structured databases. This task would be facilitated by automated procedures which can identify biological concepts in journals. Here we apply an approach for automatically mapping formal identifiers of neuroanatomical regions to text found in journal abstracts, and apply it to a large body of abstracts from the Journal of Comparative Neurology (JCN). The analyses yield over one hundred thousand brain region mentions which we map to 8,225 brain region concepts in multiple organisms. Based on the analysis of a manually annotated corpus, we estimate mentions are mapped at 95% precision and 63% recall. Our results provide insights into the patterns of publication on brain regions and species of study in the Journal, but also point to important challenges in the standardization of neuroanatomical nomenclatures. We find that many terms in the formal terminologies never appear in a JCN abstract, while conversely, many terms authors use are not reflected in the terminologies. To improve the terminologies we deposited 136 unrecognized brain regions into the Neuroscience Lexicon (NeuroLex). The training data, terminologies, normalizations, evaluations and annotated journal abstracts are freely available at

24.  Does language matter? A case study of epidemiological and public health journals, databases and professional education in French, German and Italian 
Epidemiology and public health are usually context-specific. Journals published in different languages and countries play a role both as sources of data and as channels through which evidence is incorporated into local public health practice. Databases in these languages facilitate access to relevant journals, and professional education in these languages facilitates the growth of native expertise in epidemiology and public health. However, as English has become the lingua franca of scientific communication in the era of globalisation, many journals published in non-English languages face the difficult dilemma of either switching to English and competing internationally, or sticking to the native tongue and having a restricted circulation among a local readership. This paper discusses the historical development of epidemiology and the current scene of epidemiological and public health journals, databases and professional education in three Western European languages: French, German and Italian, and examines the dynamics and struggles they have today.

25.  Mapping the literature of public health and community nursing 
Objectives: The purpose of this study was to identify the journals most cited in public health and community nursing and to determine which databases provide the most thorough indexing access to these journals. This study is part of the Medical Library Association Nursing and Allied Health Resource Section's project to map the nursing literature.
Methods: Two source journals of public health nursing, Public Health Nursing and Journal of Community Health Nursing, were subjected to citation analysis based on Bradford's Law of Scattering.
Results: A group of 18 titles comprised 34% (1,387) of the 4,100 citations, another third were dispersed among 104 journal titles, with the remaining third scattered across 703 journal titles. The core 18 journals included both of the source journals, 3 major public health journals, and several general medical and nursing journals.
Conclusions: PubMed provided the best overall indexing coverage for the journals, followed by Social Science Citation Index and CINAHL. In terms of source journal coverage, several databases provided complete coverage for the journal Public Health Nursing, while only EMBASE provided complete coverage for the Journal of Community Health Nursing.
