We shelve books according to the Library of Congress (LC) Classification system. Each book or item has a unique call number, which is a combination of letters and numbers. Think of call numbers like an address; it describes the location of a book and tells you where to find it on a shelf. 

Each call number may contain three, four, or five lines. Read each call number line by line. 



What does each line mean? 

Line 1: Defines the general subject [LB = Education Theory and Practice] 

Line 2: Classification number - defines a narrower subtopic within the specified class 

Line 3: Cutter number - represents the author's name or the title of the work

Line 4: Publication Year 

Line 5 (sometimes): Copy number - if there are multiple copies or volumes you may see a fifth line)
