Below are some definitions of the different types of editing and editors whose services you can hire or with whom you might interact if you are dealing with an agent or publisher. These terms are not applied consistently throughout the publishing world, however, so it is important that you clarify what a publishing professional will be doing.
Developmental editing is meant top address the text organization, structure, and content; for example, should there be more citations or content added for clarity? This can involve substantial rewriting and so should be done before copyediting.
Substantive editing addresses organization and structure of existing content but does not include rewriting.
Structural editing is a component of either developmental editing or substantive editing.
Line editing focuses on style, word choice, and phrasing (CMS).Some editors identify stylistic editing as a separate stage.
Mechanical editing (sometimes called technical editing) is carried out so that the writing is consistent in grammar, spelling, and punctuation and conforms to the author’s or publisher’s style. This can be a third-party style such as Chicago Manual of Style (CMS) or might be one developed by the author and/or publisher.
Copyediting prepares the document for publication and includes mechanical editing.
Proofreaders identify all types of errors and marking them, usually on a PDF, for correction. This is a term used, both inside and outside of the publishing world, in a number of ways.
