In traditional publishing, every book will be proofed before it’s released to the public. If a reader were to find more than a handful of typos or grammatical mistakes in a novel, for example, it could negatively color their reading experience (and damage the publisher’s reputation). In self-publishing, proofreading is becoming a non-negotiable part of the editorial process. Independent authors often look for ways to reduce their costs, so they’re often tempted to proofread by themselves. But as the indie book market grows and its products improve in quality, getting a professional proofread is fast becoming common practice.
