Line 2: Numerical order - 1,2, 3, 4, 1000, 2000, 3000, etc.
Line 3: Letters in alpha order, numbers in decimal order-

What Does it Mean?

Books on the shelves are arranged by the Library of Congress Classification System - a system used by most academic libraries. Every combination of numbers and letters defines a subject. For example - if you browse the N section, every book with this call number is about Art.

  • The first line of a call number contains 1, 2, or 3 letters, which broadly define the subject area. For example: K - law in general, KF - law of the United States.
  • The second line of the call number is a number, which further defines the subject. For example: books with the call number QE534.2 (Q is science) are about "Earthquakes, Seismology - General Works - 1970 to Present."
