Copy editing is like first aid for your documents. They are in pretty good shape, but need just a little help to put them in top shape. We can do a full copy edit or just proofreading.

What copy editing includes:

  • spelling
  • grammar
  • punctuation
  • capitalization
  • clarity of language
  • consistency of language

What copyediting includes

What proofreading includes:

  • spelling
  • grammar
  • punctuation
  • capitalization

But we can do much more. We can check facts. We can restructure the manuscript or sections of it, if you wish. We can enhance descriptions or dialogue. These are not part of “copy editing”, but your manuscript might need more. Let us know what your text needs, and we’ll do it for you.

If you are not sure what your manuscript needs, we can do a high-level review. We deliver a couple pages of recommendations.

What high-level recommendations include:

  • the plot
  • characters
  • descriptions
  • passages where specific improvements could be made
  • other recommendations the editor offers

David I really like this and my writing style was not lost with your editing and assistance. It still reads like I wrote the story.

Oh wow, I am crying. It is beautiful. And I am not just saying that because it is my book and all. It flows smoothly. I am pleased. I am confident I will land a contract with that. Now I feel confident. I didn’t feel that confidence before with my manuscript. Being a writer, I know that my manuscript didn’t have the smoothness I was aiming for. Thanks so much.

Five reasons to hire a professional editor

  • Hire a copy editor to be publish-ready.
  • Hire a copy editor for a fresh set of eyes.
  • Hire a copy editor to catch what you missed.
  • Hire a copy editor for accuracy and consistency.
  • Hire a copy editor to avoid looking like an amateur.

Consistency is important. You’ll look like an amateur if your style, tone or vocabulary are inconsistent. For instance, if you use US spellings, such as “center” and “neighborhood” in your manuscript, you don’t want to suddenly insert Canadian spellings, such as “centre” or “neighbourhood”. And if your protagonist is a” recruiter” in some sections, you don’t want her to suddenly become a “head hunter”. If you mention a “car” in some places and call it an automobile” in others, you will want to pick one word and stick to it. And let’s face it, if you want to sell your book south of the border, nobody will know what a “Newfie” is, nor the significance of “Meech Lake”.

I read the query letter and bawled like a baby; you did such a great job of capturing the story and my feelings towards the intended audience. The edits (for the chapters) are refreshing. I notice the improvements with the transitions of thoughts and scenes.

I can’t thank you enough for the excellent job you did. The article flows like a symphony… Of all the editors that did help me out – in my other publications – you are the best. I am very happy that I found you. and grateful for David that he recommended you. I will now submit the article for publication and if accepted I will hand you the book for your editing.
