Need a Book Editor? Here’s How I Can Help

Developmental Editing

This type of editing addresses
“big picture” content and structural issues. We’ll review your table of contents, improve your chapters’ interior organization, and make sure your writing meets the needs of your intended audience. We may also brainstorm about design and graphic elements that will enhance the clarity and appeal of your presentation.

Line Editing

Line editing addresses clarity and structural issues at the section and paragraph level. We’ll establish and implement style conventions. I will ensure that all terms that might be new to your audience are defined and that unnecessary jargon is replaced with plain terminology.


Copyediting addresses the grammar, spelling, and clarity of your sentences. My preferred professional style guide for book-length manuscripts is The Chicago Manual of Style. I use other style guides as requested.


Colleen edited several of my books, which is no surprise: I’ve specifically requested her for the job. She’s thorough, making sure each book meets its deadline. Yet, she brings everything together with such finesse that I never feel any stress. I recommend her highly as a project editor.

As project editor, Colleen has guided several of my books into safe waters, including the bestselling MacBook For Dummies. She brings an invaluable set of skills to every task: the ability to organize and prioritize, exceptional attention to detail, timely communications and concise editing. Her suggestions have improved the quality of my books with every edition, and she’s a delightful person to work with as well! Colleen has my strongest recommendation, no matter the size or complexity of the material.
