Wrong page numbering

[Josefina]

Wassermusik by T.C. Boyle (978-3499125805) has not 560 but 720 pages as can be seen here:

Amazon is actually a pretty poor source for page numbers for physical books. Instead, I checked WorldCat, which has 711. Good enough? Or can you tell me where the 9 extra pages come from?
