As part of offering you a publication contract, many toll access (pay to read) journals offer authors the option of paying a fee to make their article open access. These fees are called article processing charges (APCs), and the version of the article they apply to is the publisher’s final version. The opt-out policy applies to the author’s final draft, after peer review but before copyediting and layout. The payment of an APC will not be required as a result of this policy.
