What version of a paper should be deposited in PMC/UKPMC?
4.1The Wellcome Trust would always prefer the final, published version (which includes all changes made during the peer review process and modifications made during the copy-editing, typesetting and proofing stages) to be made available in PMC, UKPMC and other PMCI repositories at the time of publication.Please note that the Trust’s contributions must be acknowledged in all publications, quoting the grant reference number. The Trust has provided additional funding for its grantholders to cover the article-processing fees incurred by publishers. See also questions 11 and 12. 4.2However, some publishers do not allow their published version of a paper to be made available in PMC or PMCI repositories, like UKPMC. Consequently, as an absolute minimum requirement, the Trust mandates grantholders to deposit the version of the paper that is accepted for journal publication. This author manuscript includes all modifications that arise from the publishing peer-review process.
