The production process, controlled by a production editor or publisher, then takes an article through copy editing, typesetting, inclusion in a specific issue of a journal, and then printing and online publication. Academic copy editing seeks to ensure that an article conforms to the journal's house style, that all of the referencing and labelling is correct, and that the text is consistent and legible; often this work involves substantive editing and negotiating with the authors. Because the work of academic copy editors can overlap with that of authors' editors, editors employed by journal publishers often refer to themselves as “manuscript editors”. During this process, copyright is often transferred from the author to the publisher.
