Open Access & Self Archiving
Authors of original research articles are encouraged to submit the author's version of the accepted paper (the unedited manuscript) to their funding body's archive, for public release six months after publication. In addition, authors are encouraged to archive this version of the manuscript in their institution's repositories and on their personal websites, also six months after the original publication. This is in line with NPG's self-archiving policy.
Authors of original research articles can also opt to pay an article processing charge of $3,200/ £2,500 / €2,900 (+VAT where applicable) for their accepted articles to be made open access online immediately upon publication. By paying this charge, open access articles will be identified with an 'Open' logo in print and online and will be deposited for immediate publication on PubMed Central. Authors are also permitted to post the final, published PDF of their article on a website, institutional repository or other free public server, immediately on publication. Authors opting for open access are required to return an article processing charge payment form and the open access license to publish form immediately following acceptance, before the article will be processed.
Please see the FAQs for further information on the open access option or click here to download the open access payment form and open access license to publish form.
