Library Call Numbers

 Call numbers are found on the cover or spine of library materials (books, journals, and DVDs). 
 Each line of a call number represents a separate piece of information.

• The first two lines organize the item by subject. 
  • Read the first line in alphabetical order: A, B, C...
  • Read the second line as a whole number: 1, 2, 3...
• The third line is a combination of a letter and numbers and often represents the author's last name.
  • Read the letter alphabetically. Read the number as a decimal.
• The last line represents the year the item was published. 
  • Read in chronological order
