I found a gem today:
“Editors are central to any publishing project; they endeavor to reconcile the needs of the author, the reader and the publishing client.
“Editors look at the publication as a whole as well as at the detail. They ensure that the focus, structure, language, style and format of a publication suit its purpose and readership, and prepare the final copy to a standard of quality suitable for the publication.”
