Can I make changes to my paper immediately after the paper is accepted and before the copy editing begins?
That depends on the number of changes you need to make. If it is only a few minor corrections then you should wait until you are contacted by the copy editor or when you receive the proofs. If the changes are extensive, contact the editorial offices so that the paper can be pulled from its assigned issue. The revised paper will have to be sent to the scientific editor to review the changes. Once the changes are accepted, the paper will be assigned to another issue.
