A call number is like an address; it is an alpha-numeric code that tells you where the book is located on the shelf. Each book, has its own unique call number which is attached on or near the book's spine. A book's call number also appears in the library's online catalog entry. Books are sorted alphabetically first, then numerically.

Example of a call number showing: First line: the first letter of the call number represents one of the 21 major subjects. The second letter represents subdivision of the subject.  Second  line: numbers that help to define the subject area Third line: Letter and number combination that represents a code for author’s name. Fourth line: publication year.

To see which call numbers are located on what floors in both the Porter and Davis libraries please refer to our library floor plans
