Editing is the polishing before your book is published. It is at this point that you place your manuscript in the hands of your editor.
So, what are you looking to get for your dollars spent?
Well, it depends on how much you have done on your own prior to this point. Some writers will need proofreading for typos and grammar, others will want a more in-depth analysis of their story to make sure that it rings “true” with the time period in which it takes place. The editor will make sure that clothing, automobiles, literature, expressions of speech, political references, inventions, references to movies, and so on accurately reflect the calendar year (or decade) as precisely and truthfully as possible.
In one book, I researched “rabbit ears” for television reception. In another, the year of the first Cadillac Coupe de Ville was the issue, and so on.
Some editors will also see that your book is correctly formatted. Others will leave that entirely up to the publisher.
Each kind of editing has a fee attached to it. You can contract the editor to do as much—or as little—editing of your manuscript as you deem helpful.
It is at this point, while I am waiting to get my story back from the editor, that I spend time on my cover image and copy. I usually select three covers I like and then run a Facebook contest to chose the winner. This process stirs up some publicity about my upcoming book, which is a bonus.
At whatever point in the writing process you are now working— prewriting, drafting, revising, or editing—I encourage you to keep on keeping on.
2019 will be your year, if you don’t let anything distract you and you keep moving ahead toward your goal.
