The Journal of Medical Internet Research is a truly interdisciplinary resource and therefore indexed or abstracted in a wide variety of bibliographic databases, reference sources, or alert services including
-
Medline (Index Medicus), U.S. National Library of Medicine. The leading bibliographic database of worldwide biomedical literature (see Editorial and
PubMed). -
Information Science Abstracts, Information Today Inc. Designed to promote the science, management and technology of information through the abstracting of pertinent books, journals, and conference proceedings. ISA has provided worldwide library science and information science records from more than 450 publications dating back to 1966. (

INSPEC, Institution of Electrical Engineers. The leading English-language bibliographic information service providing access to the world's scientific and technical literature in physics, electrical engineering, electronics, communications, control engineering, computers and computing, and information technology.
(about INSPEC) -
Communication Abstracts is a bimonthly reference source produced at Temple University, Philadelphia, Pa., under the auspices of the School of Communications and Theater, and published by Sage Publications. It reaches a wide audience of educators, researchers, professionals and librarians in a variety of fields in the social sciences and humanities.
-
CINAHL (Cumulative Index to Nursing and Allied Health Literature) is another leading biomedical database covering nursing, allied health, biomedicine, alternative/complementary medicine, consumer health and health sciences librarianship. Originally a print index to the literature of nursing and eventually allied health information, the CINAHL-database has emerged as a comprehensive and versatile guide to an exploding body of knowledge (

5/2004: Scopus, Elsevier. After 2 years of planning, development, and initial testing by a select group of about 20 university libraries, Elsevier has finally made an official announcement of the first fully functioning version of Scopus, its highly anticipated, full-text linking, abstracting-and-indexing database. The company is currently providing access to another 30 academic libraries for final testing and user trials, and expects to have the commercial release available by Q4 2004. Scopus is designed to be an all science, comprehensive access point for a library, with coverage of 13,000 titles from over 4,000 STM publishers, plus coverage of over 100 open access journals by the summer. Scopus also simultaneously searches the scientific Web using Elsevier's science-only Internet search engine, Scirus. Elsevier has announced that the Journal of Medical Internet Research will be one of the journals that will be covered in Scopus from the beginning. (

about EBSCO) - 4/2005: JMIR content has been "donated" to the eGranay Digital Library (WiderNet project), which mirrors the entire JMIR website and makes it available offline to African universities for teaching purposes
10/2006: Back-issues permanently archived in PubMed Central
The LOCKSS system (Stanford University Libraries) preserves the Journal of Medical Internet Research at worldwide research libraries. The LOCKSS system has permission to collect, preserve, and serve this Archival Unit. This guarantees availability of JMIR content at all times and for the future.
3/2005: We are pleased to announce that the Journal of Medical Internet Research is now also a member of the Publishers International Linking Association, Inc. (PILA), which operates CrossRef, a reference linking service, which offers the scientific and scholarly community a collaborative reference linking service, through which a researcher can click on a reference citation in a journal and immediately access the cited article.
Impact Factor
The journal impact factor is a tool for ranking, evaluating, categorizing, and comparing journals; it is a measure of the frequency with which the "average article" in a journal has been cited in a particular year or period. The annual JCR (Journal Citation Reports) impact factor is a ratio between citations and recent citable items published. Thus, the impact factor of a journal is calculated by dividing the number of current year citations to the source items published in that journal during the previous two years (more about the impact factor).
The Journal of Medical Internet Research has an official impact factor of 2.9, according to the June 20th, 2007, ISI/SCI release of their 2006 Journal Citation Reports, reporting journal impact factors for the worlds' most important scholarly journals. For the first time, the J Med Internet Res (JMIR) was "officially" included - and ended up with a considerable impact factor, placing the journal on #2 in the medical informatics category (out of 20 medical informatics journals), and #6 in the very broad "Health Care Sciences & Services" journal category, which includes 56 other leading journals !
In the health informatics field, many much longer established journals, such as J BIOMED INFORM (2.3), INT J MED INFORM (1.7), and METHOD INFORM MED (1.7) - all with respected editors in the field and significant backing of commercial publishers and/or societies - have impact factors well below JMIR. The only other journal with "Internet" in its title (MED INFORM INTERNET) achieved an impact factor of only 0.6. The only journal with a slightly higher impact factor, the official journal of the American Medical Informatics Association, is very much focused on clinical informatics - but JMIR beats that journal with a better immediacy index. The immediacy index measures how quickly after publication articles are cited by others (while the impact factor takes into account only citations that occur in 1-2 years after publication). JMIR also has much faster turnaround times (days from submission to publication) than many of its competitor journals, and its unique open access policy helps uptake by other disciplines and the public - something the impact factor does not capture.
In the health services category, JMIR also beats journals such as HEALTH SERV RES, HEALTH EXPECT, AM J MANAG CARE, MED EDUC or TELEMED J E-HEALTH and J TELEMED TELECARE (the latter two have an impact factor of only 0.8).
Among the journals ranked by ISI/SCI, JMIR is the only open access journal in the health informatics field. Authors considering submitting their work to JMIR should keep in mind that the "open access advantage" goes well beyond citations and uptake within the scientific community (as measured by citations) - it also facilitates dissemination and knowledge translation to a wider audience (including knowledge endusers such as policy makers or consumers) - in other words, the open access advantage goes well beyond citations and impact factor, as measured by ISI/SCI. (see also Eysenbach G. The Open Access Advantage, http://www.jmir.org/2006/2/e8/). For many authors, this is the primary reason for why they submit their best papers to JMIR.
In fact, more important for evaluation of an individual author or paper should be the article impact factor, i.e. absolute number of citations a particular paper receives in the years after publication. We recommend that for appointment and promotion purposes evaluators should check the Web of Science database to identify how many citations a particular article has received.
Traffic, Reach, and Visibility
Another measurement of impact for electronic journals are traffic and reach rankings.
With more than 17.000 subscribers to our TOC alerts (as of 10/2006, more than PLoS Medicine), each article usually gets thousends of readers within the first days of publication.
Alexa ranks JMIR among the top 150000 sites on the web, which for a highly specialized journal is a major achievement. JMIR has more traffic and a higher reach than for example the websites of the American Medical Informatics Association (AMIA), Journal of the American Medical Informatics Association, or International Medical Informatics Association.
