High volume book such as Tuesdays with Morrie (ISBN: 0385484518) has 532 copies in the library.

If you search NLB online catalogue, it groups in the result by library locations, and shows copies available and copies owned by the library instead of the typical catalogue listing. You will need an additional click on “Click here to see full holdings detail” link to view the normal list of catalogue information.

Previously Bookjetty was not able to retrieve such information, but now the bug has been fixed. It is a really good book, or else NLB would not bother to purchase 532 copies!!! There is also an upcoming discussion on this book organised by NLB.
