The infobox gives the hardcover as 256 pages, but the publisher’s own page for ISBN 9780316595643 lists “Page Count 272 pages.” A library catalog record for the same hardcover ISBN lists “Physical Description xii, 259 pages”—that is, 259 numbered pages plus 12 pages of front matter, which is also inconsistent with 256.

Because both the official publisher listing and a library bibliographic record for the same ISBN contradict 256, the page count shown here is incorrect.
