I lied in the title.
No one knowledgeable, to my knowledge, tells writers to ignore the essentials—small stuff—like spelling and grammar and basic facts in manuscripts and books.
But as often as those things are ignored nowadays, you’d think it was part of the curriculum somewhere. Time was, it was so difficult to find a spelling error in a published book that it was noteworthy.
With the advent of do-it-yourself self-publishing, the proliferation of small presses who can’t afford copy editors and proofreaders, and even the staff cutbacks at major publishers, errors of the simplest kind now slip through regularly.
As I write this I am in the middle of a novel I was asked to review, and on several occasions the author has called those leather straps you use to control a horse “reigns.” It’s a homonym, sure, but it’s such a ridiculous error there’s no excuse for it. Likewise his saying a just-planted wheat field had been “sewn.” That one had me in stitches.
Then there are incorrect facts, if such an oxymoron exists. Some time back I read a novel by an author who has written many, many paperback Westerns for major publishers. And yet he continually referred to the “traces” on a harnessed team as if they were the lines (or reins, if you’d rather, but lines is the more common term). “Traces” are something else altogether on a harness, and he ought to know the difference—or not use the word if he doesn’t.
We all make mistakes. But there are mistakes, and there are mistakes.
Sometimes writing instructors will tell you to blow by that simple stuff in the initial draft in order to get the story down. But that is with the expectation that you’ll go back and fix it. Unfortunately, too many authors—and publishers—don’t fix it.
And that shows a lack of respect for readers. Of all things, a writer ought to be literate.
