Excuse me, is there any difference between out-of-print books and new books in Kong Lao Bookstore? Is it dirty? Is the lid damaged?

Hello, I often buy some out-of-print books from Confucius Old Books Network. As far as my experience is concerned, more than seven books will not affect reading, and there will be no pages missing. Books with missing pages in Confucius' books are generally ancient books, and stores often indicate missing pages. The standards of each store are different, but they are not much different.
