Later in 2008, Nature Publishing Group (NPG)will begin 
depositing authors accepted manuscripts with PubMed 
Central (PMC) and UK PubMed Central (UKPMC), meeting the 
requirements for authors funded by the Howard Hughes 
Medical Institute (HHMI), the National Institutes of Health 
(NIH), The Wellcome Trust, the Medical Research Council and 
a number of other major funders in the US, the UK and 
Canada who mandate deposition in either PMC or UKPMC. NPG 
hopes to extend the service to other archives and 
repositories in future. NPG will deposit the accepted 
version of the authors manuscript on acceptance, setting a 
public release date of 6-months post-publication. There 
will be no charge to authors or funders for the service.

Oxford Journals,too,will manage the mandated NIH deposit. 
Biomedical articles that have been published in Oxford 
Journals and funded by the NIH will now be deposited into  
PMC. Now any NIH-funded authors who publish their articles 
in an Oxford journal will not need to deposit them into PMC 
themselves  Oxford Journals will do so for no charge on 
their behalf. Manuscripts which are NIH funded and already 
open access will be available immediately on PMC. However, 
only the final published articles rather than original 
submitted versions will be available from PMC.
