How to Read a Call Number

 How to Read a Call Number

"Library of Congress" System, NOT Dewey Decimal!

Books are arranged by call number, in both alphabetical and numerical order. Call numbers appear from top to bottom on the book:

LB
2395
.C648
1991

  • The first letter of the call number represents the subject. In the example above, L represents education, and LB is theory and practice of education.
  • The second letter represents a subdivision of that subject.
  • The first set of numbers refers to an area of study within that subdivision.
  • The second set of numbers is a code that represents the author's name, book title, and subject. It should be read as a decimal, i.e., .648.
  • The last number represents the year of publication.
