Yes, changes can be made at the proofreading stage; however, we ask editors to keep the minimum number of essential changes so that the number of pages should not get changed. Remember, at the proofreading stage, we have already completed a considerable amount of copyediting work and metadata preparation for online publication. Requests for numerous small changes, which might appear to be minor, may actually result in considerable additional work to regenerate metadata. We ask editors to ensure before submission that all manuscripts are thoroughly reviewed and edited to avoid requesting substantial changes during the production process.
