Editors, especially at a publishing house or a newspaper, are responsible for reading, reviewing and editing written texts. Editors may also suggest projects and work closely with authors. In contrast to proofreaders, who are checking for formalities such as spelling, punctuation, etc., editors pay more attention to content, particularly its structure and organisation. They may omit, add or reorganise words, sentences or even whole paragraphs or chapters. Editors should have excellent writing skills and often have wide experience in a particular subject, so they can ensure a text features the correct specialist terminology and reads well. This is particularly important when a native speaker is editing copy written by a non-native speaker.
