Reading Call Numbers

There are two major call number systems used in the libraries: the Dewey Decimal and Library of Congress classification schemes. The first line of a call number, as it appears on a physical item, is a broad subject classification. The subsequent lines are combinations of letters and numbers that organize items into narrower, related categories.

Library of Congress  Dewey Decimal
HB   Alphabetically 
​615  Whole number
573.3  Whole number, followed by decimal
 
C518  Alphabetically, then decimals
(may be followed by another letter)
.W932A  Alphabetically, then decimals 
2018  Publication Date, shelves chronologically e.g., 573.3 W932A shelves before 573.3 W94A  

See How to Read Call Numbers from the University of Berkeley Library for more details about LC call numbers.
