What exactly is “editing”? It’s common for someone to ask for a “proofread” when their content actually needs significant revisions. And occasionally, when someone hears that you’re an editor, their eyes light up and they ask if you can get their book of poems published.

If you search the internet, you’ll find many—often conflicting—definitions of editing. Here, I’ll explain two types of editing that Wheelhouse Editorial provides: substantive editing and copyediting.

Substantive Editing

Also known as line editing, structural editing, and content editing, substantive editing is more about writing craft than fixing errors.  Substantive editing reworks the text to improve flow. It address word choices and sentence/paragraph structure. It requires good judgment, experience, and a sense of what makes good writing good, in addition to a firm grasp of grammar and punctuation rules. Writing has been a lifelong love of mine, so substantive editing is my favorite type of editing!


Copyediting is a more technical process than line editing. Wikipedia defines it as “the process of reviewing and correcting written material to improve accuracy, readability, and fitness for its purpose, and to ensure that it is free of error, omission, inconsistency, and repetition.” A copyeditor refers to a style guide (such as the Chicago Manual of Style, the Associated Press Stylebook, or others, depending on the content) and often creates a style sheet that explains how style rules apply to your specific content. A copyedit is typically the last edit before content is typeset (after which a proofread would follow).

The New York Book Editors website contains a wonderful comparison of substantive editing and copyediting. They sum it up nicely: “While your [substantive] editor will probably not have the Chicago Manual of Style committed to memory, your copyeditor might.”

The Bigger Picture

Even though there are many gray areas among editing definitions, one thing is certain: in an ideal world, a developmental edit (big picture edit) should come before a substantive edit, which heralds a copyedit, which precedes a proofread. I repeat: in an ideal world. This is very often not the case, and I can work with you to determine what your project needs at this time in its very dynamic life cycle.

In addition to substantive editing and copyediting, Wheelhouse Editorial provides project management and fact checking services. I don’t officially do developmental editing at this time, although I do share insights into the bigger picture of a manuscript as they arise. For large projects that require more hands on deck, I can assemble a team of editors, proofreaders, and/or fact checkers to make sure the quality of the work meets my high standards.
