In past posts I have stated that editing a book is never done. There is always someone who can find an error. A faithful reader actually found an error in Grapes of Rome. Traumatizing. Mason7751 found a legitimate error in the book. Thank you!
Now I go to fix the error, and I find four more errors, tiny ones, that most would never notice, and they were so small I won’t even mention what they were. The error Mason found wasn’t that bad either, but it was bad enough to fix. So I fixed those errors and re-uploaded the files.
I love people telling me if something is wrong. What I do not like is so called reviewers pointing out that there are errors in the book. In a fourth edition of a Robert Heinlein book, A Door Into Summer I found four errors. These were major errors that any editor should have found. Yet here is a great author with many books, and those four errors stood out like elephantiasis. If that can happen, then a fledgling author like myself has no chance.
What I am telling you is that if a book has some errors, but it was readable and good, then forget talking about the errors. Email the author and let the author know. In most cases it will be fixed.
