The meaning of call number
Call number, also called book code or call number, consists of classification number and book number, with a crown number if necessary. It shows the location of the collection, is the code for library sorting, checking, borrowing, returning and registering, and is the main basis for literature borrowing and collection inventory. Generally, it consists of several groups of numbers arranged by branches, which are often printed on the upper left corner of the catalog card, on the book label below the spine, and above the title page or back cover of the book.
A call number can only represent one kind of books, because the shelving methods of library books can basically be divided into two categories: classified shelving and formal shelving. Therefore, call numbers can basically be divided into two categories: classified call numbers and formal call numbers.
