Professional Editorial Standards 

The skills listed in this publication are those most commonly required for editing English-language text, whether on paper or on screen. The editor's functions start when the writer declares the manuscript more or less complete and continue through to the point at which it is ready for publication, regardless of the medium. Editors perform many tasks along the way, including structural editing, stylistic editing, copy editing, markup/coding, and proofreading. The technologies used in editing and in publishing change, but the fundamental tasks and the editorial skills required to work with words remain relatively constant.
