Editing "copy" is the basic process of editing "copy" or the words written by a journalist. Usually this is done by an "editor," someone whose role it is to review the writing of any number of journalists. But this is not always the case. In television or radio this role may fall upon a producer and the writer may be referred to as a correspondent. And with more specialization, some news organizations have employed "fact checkers" or "researchers" who also edit the copy, looking mostly at facts rather than style or composition.
