Hi Lea, and welcome back. the validation process is as in-depth as you want to make it. You definitely did the right thing to reject a book with whole chapters mangled. With books with one word missing at the end of each page I would try to fill in the missing word, but if there's a word missing on every line, I would reject. With books, some people just check to see that the minimum required info--copyright etc--is present, while others read through the whole book and correct all the errors they find. It's really up to you how much or how little you want to do. Enjoy the validating, Kellie
