    Attempts to use the internet to free up access to the world's biomedical literature have resulted in several similarly named initiatives emerging over the past two years.

    The debates around free access are some of the most important that have taken place in the three centuries of scientific publishing.1 Yet confusion about who wants to do what to whom is hampering this debate. This attempt to dispel some of the confusion was up to date at the time of writing, but given the speed at which medicine's electronic landscape is changing, it is likely to date fast.

It covers 4300 journals devoted to medicine, nursing, dentistry, veterinary medicine, healthcare systems, and the preclinical sciences. PubMed also provides access to life science journals that are not indexed by Medline but have submitted their full text to PubMed Central (see below).

    As well as providing access to these abstracts and citations, PubMed links to more than 2000 websites that provide full text articles (figure). Access to these full text articles usually entails registration, subscription fees, or some other form of payment, although bmj.com is free.

    In the four years since PubMed was …
