Reading and Finding a Call Number
After you have searched the Sonoma Valley High School Public Access Catalog and found the item you are looking for, look carefully at the record for the call number. Call numbers are the unique address of every item in the Library. The call number is based on the Dewey Decimal System.
In our example, the call number is: 796.323 AUE

796 Read the first line as a whole number 1, 2, 10, 20, 350, 796, etc.
.323 Read the next number as a decimal: .009 .01 .3 .323, etc. ...
.AUE Read the second line as a combination of letters: AUE, BAK, COL, DEN, etc.
1987 Read the third line as the year the item was orginally published.
NOTE: The call number is on the bottom spine of the book. Read each line of the call number separately.
