How to Become a Book Editor

Occasionally, I’m asked how to become an editor. There is no single way to do this or official requirements to become one, but I’ve compiled some information here for people who are sticklers for grammar, love words, enjoy curling up with a good book, get regularly asked to correct their friends’ writing, and are considering this career path.

All the editors I know came to be so by vastly different means. Some interned at a local publishing company; some started as authors; some went to university for English or journalism; some didn’t have any post-secondary education.

As for my own journey—I received a BA in English, did an editing internship at a periodical, and studied publishing at Toronto Metropolitan University. After my education, I worked in graphic design before becoming the managing editor at a nerdy magazine and then a small press. Now, I’m an independent editor.

There’s no “right” or “wrong” way along this career path, but read on for some questions you should ask yourself and resources for training.

Should I Work Freelance or In-House?

You can either work for yourself or for a publishing company, and there are pros and cons to both. Getting a job at a press, particularly one of the large ones, may require formal training and experience, but if you intern or get hired as an editorial assistant, they may train you on the job. These companies usually have knowledge and resources, and they tend to take on authors with big potential. You might even work on established authors’ books. Salary and health benefits, if they offer them, are a big plus, too. If you work at a small press, you’ll likely get to pick the books you work on.

Starting your own editing business should be taken on with just as much, if not more, care as working for a publishing company. Yes, anyone can start a business, but you’re positioning yourself as an expert in a field, so you should actually be an expert in the field. You need some sort of training and experience to ensure the authors who hire you are in good hands. When you freelance, you manage your own finances and set your own hours and rates (for an idea of what to charge, check out these median numbers from the Editorial Freelancers Association). 

Technically, you can pick and choose what projects you work on, but, particularly when you’re first starting out as a freelancer, you may not have the privilege of doing so. You’ll likely be taking on any writer who comes to you and is willing to pay your rates. This means you might be working on some rough books by authors who really need more practice before they’re published, but it’s not your job to tell them that. You just do your best to work with them on getting the book into shape and providing the service you’ve been paid for. 

You can also send your resume to book publishers and ask to be added to their freelancer pool. They will likely ask you to take an editing test before sending work your way.

What Type of Editing Should I Offer?

Some editors specialize in one type of editing, while others offer multiple services. Here is an overview of the four types of editing, each geared towards a specific phase of the manuscript’s progress.

1. Developmental Editing

Also known as structural or content editing, developmental editing is all about the big picture. It’s the first step after a draft is complete, and should occur before correcting grammar, punctuation, or word choice, because this stage usually includes substantial rewriting; no need to worry about that run-on sentence when the entire paragraph is likely to change!

Developmental editors analyze many elements of a story, including structure, tone, character voice, point(s) of view, worldbuilding, pacing, dialogue, consistency, plot development, and character arcs. Fixing plot holes, deleting or adding scenes, adding foreshadowing—this is all within the realm of developmental editing. 

These editors also tend to spend the most back and forth time with the author as they work together to solve macro story issues. A significant part of the job is learning how to communicate with the author and helping them write their story the way they would write it, not the way you would write it. Some authors feel threatened or irritated when receiving feedback on work they’ve spent years refining, and developmental editors can help put their minds at ease by being willing to work together to solve problems instead of dictating answers.

2. Line Editing

Line editors focus on paragraph-level issues. They are not concerned with grammar or spelling (that comes later), but tone, clarity, and word choice. They want to make your manuscript as tight as possible. Some common areas line editors focus on: writing in a passive voice, using too many adverbs or adjectives, telling and showing, redundancy, repetition, misplaced modifiers, dialogue, tenses.

3. Copy Editing

Copy editors fix inconsistencies and grammar. They focus on technical things like commas, capitalization, spelling, dangling modifiers, etc. They also use a style guide, provided by the publisher or author, or created themselves, to ensure consistency when there is no right or wrong answer. For example, does the book use American, Canadian, or British spelling? Are there spaces between em dashes? Is the serial comma used? Are subheaders bolded? Are numbers spelled out or written in numerals? Style sheets will also include made-up words or unique names specific to the novel.

Some editors combine line and copy editing into one service. Particularly for indie authors on a budget, it can get expensive when you need a different editor for each stage, so it’s helpful when a single editor offers both. Some editors even combine developmental, line, and copy edits into one service, but I only recommend doing that if the manuscript doesn’t need a lot of big picture changes.

4. Proofreading

A proofread is usually done after a book has been laid out, or typeset, into a file ready for print. This is one last chance to double-check spellings, remove wayward commas, fix widows or orphans, and catch any last grammatical errors. Proofreaders also attend to indentation, line spacing, and header styles, and they consult the style sheet to ensure consistency. 

This type of editing should not be combined with any of the others, because it is the last check for minor errors in text and layout before the book goes to print.

You may want to try out each of these editing styles to determine what area you’d like to focus on (or if you’d like to focus on multiple areas). They each require different skillsets and approaches. Taking courses or reading books on the topic can be a great place to start. 

Will I Specialize in a Particular Genre?

Developmental editors in particular may wish to focus on a particular genre or group of genres as a specialty. Different genres have different styles, conventions, and tropes, and understanding these conventions on a deep level will allow you to accomplish more valuable critiques. Editor Sophie Playle’s post, “Should I Hire an Editor in My Genre?”, provides a useful overview on what an author might be looking for in regards to their editor’s familiarity with a genre.

Where Should I Receive Training?

Many editors have degrees in English, communications, or journalism. There are no official requirements to become an editor, but these can be helpful to lay a foundation for reading, writing, and communication.

If you’re looking for some training in editing specifically, the following are universities, organizations, and individuals I’m aware of that offer courses. You don’t necessarily need to limit yourself to your own country of origin when choosing where to take online training, but note that Canada, the US, and the UK do have varied spelling conventions and there may be a few other differences. As an editor, you’ll probably want to be aware of what those are anyway, unless you only intend on working in or taking clients from your home country. Universities and colleges from your home country may offer internship and local opportunities that you can only take advantage of if you are a resident of that country, as well.

You don’t need to take courses or get a degree to become an editor. It is only one route; it’s a quick way to get a lot of information and training in one place, but it’s also expensive. 

Other opportunities for training include internships and mentorships at publishing companies, magazines, newspapers, or other publications. Large publishers will have a submission process, while you may need to approach small companies to ask if they’d be willing to take you under their wing. Small presses can be a great way to get some training, but make sure they are run by people who actually know what they’re doing (check out the books—the covers, blurbs, designs, and stories—they’ve published to see if they produce quality content). You can also start teaching yourself by joining a writers’ critique group and reading books or other free resources on the topic.

Other Resources

It should be no surprise that a great way to learn about editing is to read! In particular, read lots of the books in the genre you intend to specialize in; and read them critically, noting what techniques keep your attention, why the dialogue is interesting (or not), how the author implies questions that keep you turning pages, how characters are developed, etc. Below are nonfiction books and podcasts that you may find helpful, as well as organizations you may be interested in joining.


  • An Editor’s Guide to Working with Authors by Barbara Sjoholm (2011). This is a great place to start for developmental editors, with information on how to read a manuscript, organize your notes, write an editorial letter, and more.
  • Self-Editing for Fiction Writers: How to Edit Yourself Into Print by Renni Browne and Dave King (2004). This is a good read if you are just starting to learn the nuts and bolts of editing. It’s geared towards writers, but it’s got a lot of good advice on showing vs. telling, which is something you want to be looking out for as a developmental or line editor. 
  • How to Write Dazzling Dialogue: The Fastest Way to Improve Any Manuscript by James Scott Bell. Poor dialogue is one of the most common issues you’ll see in new writers, so it’s helpful to know what problems to look for and how to fix them. This book is geared towards writers, but it contains the best advice on dialogue I’ve read and is useful for an editor as well.
  • The Copyeditor’s Handbook: A Guide for Book Publishing and Corporate Communications by Amy Einsohn and Marilyn Schwartz (2019). This is great if you want to get into copyediting, as it goes in-depth into copyeditor’s issues, like punctuation, spelling, capitalization, treatment of numbers, tables, graphs, and markup. I don’t use it much, because I’m mainly a developmental editor, and I’ll consult Grammatically Correct when I need reminders on word usage. 
  • Grammatically Correct: The Essential Guide to Spelling, Style, Usage, Grammar, and Punctuation by Anne Stilman (2010). This is one of those books you’ll want to buy and keep for reference after you read it. It’s got a lot of helpful reminders on frequently misused words, punctuation, structure, syntax, style, and more. 
  • The Subversive Copy Editor by Carol Fisher Saller (2009). Editing isn’t just about the mechanics—it’s also about working with authors, and this book gets into that topic extensively. 
  • What Editors Do: The Art, Craft, and Business of Book Editing by Various Contributors (2017). This is a collection of articles by a variety of editors on topics like acquisitions, the editing process, case studies, and more.
  • Dreyer’s English by Benjamin Dreyer (2019). Written by Random House’s copy chief, this is a useful style guide that I’d recommend over The Elements of Style.


  • The Editing Podcast. Hosted by fiction editor Louise Harnby and nonfiction editor Denise Cowle, this podcast is gold. There’s so much wisdom here, especially if you’re just starting out. 
  • Grammar Girl. Founder of the Quick and Dirty Tips network Mignon Fogarty delves into words and language every week in this delightful podcast. 
  • Story Chat Radio. Book editors Carly Hayward and Jeni Chappelle break down the structure and storytelling techniques in movies with a dash of humour.
  • Writing Excuses. Though this podcast is for writers, the episodes delve into lots of topics that are useful for editors, too.
  • The Worldbuilder’s Tavern. Also geared towards writers, this podcast is particularly useful if you plan on editing sci-fi and fantasy, because it breaks down the worldbuilding of beloved stories.
