Copyright form
Upon submission of an article, authors are requested to complete a copyright form, which transfers (or for some journals, licenses) copyright in all original material in the article to IOP or its relevant publishing partner if the article is accepted.
IOP requires a copyright form to be signed, whether or not the article will be published under the subscription model or under the gold open access model. The copyright form must be filled in correctly, signed, dated and submitted to IOP (for most of our journals this is done via the Author Centre) before an article can be accepted.
For further information on completing the copyright form, please see the Copyright FAQs page.
