After submitting the form below, you will receive an Open Access License to Publish (OA LtP) Form that needs to be signed and returned. If you order open access for your article, you will be charged an article-processing charge (APC). The invoice will be sent to you after the license to publish document has been returned.
We will publish a correction article and update the metadata and full text of the original article, which means that copyright, license and open access information in the article will be updated.
Please note that it is not possible to cancel this order and ensure you read our Retrospective open access for transformative and hybrid journals policy (under the 'Other OA policies' section) before submitting your request.
