The JCB, a leader in providing free, public access to  
science, has announced its intention to deposit all JCB 
content in PubMed Central (PMC) where it will available to 
the public six months after publication beginning in 
November 2007. Since January 2001, JBC has released its 
content six months after publication, and has provided 
immediate free-access to colleagues in 143 developing 
nations. 

    The change in policy stems from the realization that 
XML content may have greater longevity than PDF files. JBC 
also recognizes the necessity for multiple archives of its 
electronic content as print is phased out.

    Additional placement of JCB content in the PMC archive 
ensures permanent and free access in a central repository 
alongside research from other leading journals. The routine 
deposit in PMC represents de facto compliance for authors 
with policies formulated by many funding agencies requiring 
access to research they have funded after a short delay. 
This service will be free of charge to authors. 
    If authors wish to make their papers available sooner, 
they may post the final, published, PDF version on their 
own websites immediately after publication.
