Book index number What do you think of the library's book index number? Are all libraries the same?

The book index number includes two parts, one is the classification number, and the other is the distinguishing number. The classification numbers in the book index numbers of all libraries are uniform, but the division numbers are not uniform, so the book index numbers of all libraries are not the same.

The (1) identification number indicates the different varieties of this kind of books in our library. For example, a library bought many kinds of books on C Programming, including those edited by Zhang San and Li Si.
