The Publication Form (also called "license to publish") can be found here.
Yes - all author signatures are needed on the Publication Form.
- The corresponding author should sign the Publication Agreement (section 1)
- All authors should sign the Letter of Responsibility (section 2)
- All authors should sign the Disclosure of Funding and Competing Interests section (section 3)
Authors can sign electronically using a resource like HelloSign. This may be especially helpful if authors are at different institutions or geographically separated.
There is no need to have all of the signatures on one form - we accept different pages each signed by a different author.
If there are more authors than will fit on the form, please add additional sheets.
As soon as possible after acceptance of your paper, please upload the completed form signed by all authors to your online account as supplementary file (choose the "License to Publish" category).
If an author refuses to sign or is non-responsive over an extended period of time then it may be that this author does not meet all authorship criteria (see Who should be listed as author and sign the publication form? (authorship criteria)). The only exception is if an author is deceased. To drop an author at this stage for refusal to sign is uncommon, but if it is required, please read How to change (add/drop) authors after peer-review but before publication.
