. • Each material in the library has its own unique call number. • It appears in the library’s on-line catalog. • Understanding the Call Numbers and the Classification System will make it easier for you to retrieve Library materials.
The call number is also attached to the spine of the book. • It is like an address that tells you where the library material is located. • It also provides the information such as the subject, First letter of the author’s last name and the year of publication.
