The other roles of commissioning editors vary between companies. Usually they are also responsible for ensuring that authors under contract deliver typescripts to specification and on time. They thus have an author management role. They usually have responsibility for ensuring that typescripts are of sufficient quality. In this, especially in textbook and reference publishing, commissioning editors may be assisted by development editors or assistant editors. Furthermore, in textbook companies, this role is responsible for managing title revisions, signing new authors, and ensuring products are profitable. In some (usually small) companies, commissioning editors are also responsible for overseeing the
copy-editing, typesetting, proofreading, and design of books, although in other companies this responsibility is assumed by other staff e.g. Managing Editors, House Editors, and Production Editors. Commissioning editors are also often responsible for managing books that have already been published, for example by ensuring that stock levels are adequate and advising on when a book needs to be reprinted. == Commissioning process ==
