About BMJ

Welcome to bmj.com

The BMJ is an international peer reviewed medical journal and a fully “online first” publication. Our publishing model—”continuous publication”— means that all articles appear on bmj.com before being included in an issue of the print journal. The website is updated daily with the BMJ’s latest original research, education, news, and comment articles, as well as podcasts, videos, and blogs.

All the BMJ’s original research is published in full on bmj.com, with open access and no limits on word counts. We do not charge authors or readers for research articles, nor for other articles arising from work funded by open access grants. The BMJ’s vision is to be the world’s most influential and widely read medical journal. Our mission is to lead the debate on health and to engage, inform, and stimulate doctors, researchers, and other health professionals in ways that will improve outcomes for patients. We aim to help doctors to make better decisions. The BMJ team is based mainly in London, although we also have editors elsewhere in Europe and in the US.

Owner and publisher

The BMJ is published by BMJ Publishing Group Ltd, a wholly owned subsidiary of the British Medical Association. The editor of the BMJ is Fiona Godlee.

The BMA grants editorial freedom to the editor of the BMJ. The views expressed in the journal are those of the authors and may not necessarily comply with BMA policy. The BMJ follows guidelines on editorial independence produced by the World Association of Medical Editors and the code on good publication practice produced by the Committee on Publication Ethics.

The BMJ's sources of revenue

The BMJ receives revenue from a range of sources, to ensure wide and affordable access while maintaining high standards of quality and full editorial independence. The sources of income include subscriptions from institutions and individuals; classified advertising for jobs and courses; display advertising for pharmaceutical and non-pharmaceutical products; events (exhibitions, sponsorship, and visitor fees); sale of reprints, rights, and royalties; and sponsorship.

Separation is maintained between the editorial team and the advertising and sponsorship sales teams. Where sponsorship has been obtained for any BMJ content—for example, as a result of an unrestricted educational grant—this is clearly indicated.

Reach and impact

About 1.3 million unique users download 5.9 million pages from bmj.com each month (ABCe audit, October 2008). The BMJ’s Impact Factor is 12.827 (ISI Web of Science, 2008).

We audit the performance of BMJ research articles, using a wide range of indicators to assess their impact on readers and their dissemination to the wider world.

The print BMJ has a long history and has been published without interruption since 1840, when it began as the Provincial Medical and Surgical Journal. The print BMJ is now published weekly in three editions that vary only in their advertising content. Together, their weekly circulation totals about 122 000 copies, of which 10 000 are distributed outside Britain. International editions reach another 55 000 readers. The BMJ is printed on 100% recycled paper and mailed in a recyclable wrapper.

In May 1995 the BMJ became the first general medical journal to launch itself into cyberspace as bmj.com going on to win Best Business Product or Service at the PPAi Interactive Publishing Awards 2000, Best Integration of Media at the AOP UK Interactive Publishing Awards 2002, and to be voted one of the web's five most useful health sites by Guardian Online readers and contributors in 2004. Continuous daily publication on bmj.com started in July 2008, with all content appearing online before print publication. We abridge many articles for the print BMJ, including all research.

In July 2008 the BMJ was named Medical Publication of the Year at the Medical Journalist Association's awards in London. BMJ News Editor Annabel Ferriman was jointly awarded Health Editor of the Year award, and Susan Mayor was named Medical Journalist of the Year.

PMC Overview

PubMed Central is a free digital archive of biomedical and life sciences journal literature at the U.S. National Institutes of Health (NIH), developed and managed by NIH's National Center for Biotechnology Information (NCBI) in the National Library of Medicine (NLM). With PubMed Central, NLM has taken the lead in preserving and maintaining access to the electronic literature, just as it has done for decades with the printed biomedical literature. PubMed Central aims to fill the role of a world class library in the digital age. It is not a journal publisher. NLM believes that giving all users free access to the material in PubMed Central is the best way to ensure the durability and utility of the archive as technology changes over time.

PubMed Central follows in the footsteps of other highly successful and useful services that NCBI has developed for the worldwide scientific community: GenBank, the genetic sequence data repository, and PubMed, the database of citations and abstracts to biomedical and other life science journal literature. GenBank, and the tools provided by NCBI for searching and manipulating its contents, have been a boon to molecular biologists and have helped advance developments in the field. PubMed (which encompasses Medline) is the database of choice, for researchers and clinicians alike, to locate relevant articles and, in many cases, link directly to a publisher's site for the full text.

Participation by publishers in PubMed Central (PMC) is voluntary, although participating journals must meet certain editorial standards. (See How to Join PMC.) Journals are encouraged to deposit all their content (and not just research papers or other selected material) in PMC so that the archive becomes a true digital counterpart to NLM's extensive collection of print journals. In line with this objective, NLM has digitized earlier print issues of many of the journals that are in PMC. Although immediate free access to all content is most desirable, a journal may delay release of its full text in PMC for some period of time after publication. See the Deposit and Access Policies for more information.

A journal is guaranteed access to a copy of its deposited data upon request, at no cost. PubMed Central does not claim copyright on any material deposited in the archive. Copyright remains with the journal publisher or with individual authors, whichever is applicable.

The value of PubMed Central, in addition to its role as an archive, lies in what can be done when data from diverse sources is stored in a common format in a single repository. GenBank has proven the advantages of collecting DNA sequences in a central repository with a common format. You get more rapid searching, manipulation, and cross-linking of the complete collection, and all the benefits that derive from that. Similarly, with PubMed Central, one can quickly search the entire body of full-text articles and locate relevant material regardless of its source. It also makes it possible to integrate the literature with a variety of other information resources such as sequence databases and other factual databases that are available to scientists, clinicians and everyone else interested in the life sciences. The intentional and serendipitous discoveries that such links might foster excite us and stimulate us to move forward.

Most journals now have online publishing operations and there is a growing tendency to publish material online only, to the exclusion of print. This literature must be preserved in a form that ensures unrestricted access to it over the longer term. This is what NLM has undertaken to do. We invite all journals to join those that have already committed to creating this resource for people all over the world. ---> Read More . . .
