Yes, if your work has been published as a standard article in an Open Select (hybrid) journal, you can choose to make it gold open access at a later date:
1. Email our OA Support Team at firstname.lastname@example.org explaining that you wish to make your article open access. Please include the title and DOI of your article.
2. You will receive an invoice for the article publishing charge (APC) to make your article OA, along with a new copyright form to sign.
3. Your article will then be made open access so that it is permanently available for anyone to read, anywhere.
Standard APCs apply if you are making your article OA retrospectively, however discounts may be available if your institution has an OA membership or is part of an open access agreement. To find out if you are eligible for a discount under these agreements please contact our OA Support Team (email@example.com).
