Reading Dewey Decimal Call Numbers

  • Every Dewey Decimal (DDC) call number begins with three numbers (003 is never written as 3 in DDC), some with decimal numbers followed by various letters, and/or number combinations.
  • Numbers to the left of the decimal point in Dewey call numbers are whole numbers. Therefore, 015 comes before 150.
  • Numbers to the right of the decimal point in DDC call numbers are decimal numbers. Therefore, 970.13 comes before 970.3.

The following call numbers are in correct shelf order for the reasons given:

468.642 Ab2a 468.642 Al1c 1995 - Al comes after Ab 970 T16n - 970 (970.000) is a larger number than 468.642 970 We 37 - We comes after T alphabetically 970.01 C72: - 970.01 is larger than 970 (970.0000) 970.13 B61d - 970.13 is larger than 970.1 970.3 B36o - 970.3 (970.300) is larger than 970.13 (970.130)
