However, most proofreaders only give bits of feedback: many won’t read your entire manuscript, or not within the deadline.
Unfortunately, in real life, something often comes up, they are busy or forget the deadline. My experience is that from a pool of ten proofreaders, in the end, only two or three will deliver valuable feedback. Keep this in mind when asking people to proofread. Ask if they are available and whether they can provide their feedback by a specific date.
In my experience, the best way to get specific, useful feedback is to ask proofreaders the following three questions:
- Which bits did you like?
- Which bits put you to sleep?
- What did you miss in the book?
Finally, create a system for yourself. How will you process the feedback? If all ten of your proofreaders send you a document with comments, it is still quite a job to review everything and determine what you can and cannot adopt. Include time for this in your book writing schedule. And keep in mind that all this feedback makes your book better.
