** Today the DDC (Dewey Decimal Classification system) is published in 4 volumes. The first volume consists of the manual and tables. These tables contain numbers that are appended to numbers found in the schedules. When building a Dewey number we never start with Volume 1. Volumes 2 & 3 are the actual schedules. Here is where you'll find your base numbers. Volume 4 contains the Relative Index, which we'll see in a few minutes.
