This document summarizes a training session on the Dewey Decimal Classification system. It discusses classifying works with multiple subjects or disciplines, using interdisciplinary numbers, and determining the main focus of a work. Standard subdivisions and number building techniques are also covered, including using tables 1-4 to further specify classifications. An assignment is due January 21st reviewing these classification concepts.
