What are open access journals?

Open-access journals are scholarly journals available online to everyone without restriction. Most of these journals are available 12 months after publication but some are available immediately.

Some major sources of open access journals in biomedicine :

• PubMed Central® (PMC) :         A free archive of biomedical and life sciences journal literature at the U.S. National Institutes of Health's National Library of Medicine. Launched in February 2000, PMC is a repository for journal literature deposited by participating publishers as well as authors worldwide. Publishers and individual authors continue to hold copyright on their material in PMC and users must abide by the terms defined by the copyright holder.
• Europe PubMed Central :   
  The UK PubMed Central, mirrored on the US PMC was funded and developed by the Wellcome Trust and the British Library and available in January 2007. On 1 November 2012, it was rebranded Europe PubMed Central to reflect its wider international scope and content. This will increase the volume of open access material available to researchers, academics and the public.
• BioMed Central  
• Free Medical Journals Online  Most titles are free 6 months after publication, some after a year.
