Use of Authoritative Editing Style Guides
As a developmental editor, you won’t be copyediting, but you do need to be familiar with the authoritative editing style guides copy editors use.

Basic Editing Style Guides
Most of my clients have wanted me to follow The Chicago Manual of Style with some variations. That is standard for book publishing, so it pays to become familiar with CMOS. If you have private clients, you can let them know about this standard and explain that your edits will reflect it.
Tell your author which dictionary you’re using (if your client is a publisher, they may have a preferred dictionary; invest in owning a copy yourself, whether in print or online). CMOS prefers Merriam-Webster (the most recent edition), so that’s what I use.
The style manual is the main place you look to make decisions about how to edit the mechanics of a manuscript. Occasionally your client will prefer a different approach. For example, I have one client who basically follows CMOS but prefers to use no serial commas. This is called the house style.
We’re not copy editors, but we need to be conversant with style and other copyediting considerations to communicate effectively with other members of the editorial team and with the author.
Using Usage Guides
A usage guide, such as Garner’s Modern American Usage, offers information on usage, including examples of incorrect usage, to help you see where the author you’re editing may be going wrong.
This is not to say that you should query every questionable word choice your author makes (that’s the copy editor’s job), just that when you feel the usage is incorrect (and therefore could be confusing to readers), a usage guide helps you ensure that you’re making defensible edits, not just getting on a soapbox about your pet peeves.
Classic usage guides include Fowler’s Modern English Usage, Bernstein’s The Careful Writer, and Skillin and Gay’s Words Into Type. Browsing these guides at the library can be a very educational use of a Saturday afternoon. But don’t be confused by people who say that Fowler’s is easier to use than CMOS; they’re comparing a usage guide with a style guide, and they’re two different things.
One of the most valuable uses for Garner (or other usage guides) is to verify the correct expression of phrases. I cannot tell you how often I encounter incorrect phrases such as “tow the line” for “toe the line” and “in the throws of” for “in the throes of.” A quick glance at Garner will verify if an edit is in order.
Following the Author’s Preference
Line editing and copyediting for fiction are very different from nonfiction and are as much an art as a science. So, you have to be careful that any line edits you make are appropriate and necessary.
One of the publishers I do developmental editing for recommends following the author’s preferences and just making sure those preferences are consistently applied. If an author has a style quirk—such as using spaces around em dashes—and it’s not wrong, just different from what CMOS recommends, we’re asked to let it stand and just be sure that all em dashes are treated the same. In general, this is not a bad approach for most style questions you’ll encounter as a DE.

How to Read Like an Editor
Book development editors don’t read books the way readers do. To sharpen your developmental editing skills, you need to learn to read like an editor does (instead of the way a reader does). When you’re a reader, you enter the author’s world. You willingly suspend your disbelief in order to experience this world. That doesn’t…

Story Editing as a Second Career
When I teach developmental editing classes, I get a lot of students transitioning from other careers. They’re often lawyers, social workers, and teachers – though I’ve also taught actors, accountants, and engineers, among others. What they have in common is that they love stories and want to explore whether book editing (story editing/developmental editing) is…

Getting Started Teaching How-To Classes
If you’re a developmental editor, you’ve probably occasionally thought about teaching a class for writers—perhaps as a means to let people get to know you before they invest in the expense of a full developmental edit or because you want to help them solve some common writing problems before they finish their first draft or…
