Course Description

Does this book on houseplants go in gardening (635.9), botany (581.6), or interior decorating (747)? This is not a drill! For many librarians responsible for cataloging and classifying, this is a common scenario and dilemma when processing new materials. Whether you’re new to this task or needing a refresher, a solid knowledge of the basics of Dewey Decimal Classification will help you feel more comfortable using this important tool.

This class will cover assigning classification numbers with correct meanings in the Dewey hierarchy, as well as assigning numbers when a topic might fall under more than one discipline. Other topics covered include choosing the right number based on Notes and Manual entries, building numbers using the tables, and a look at OCLC’s WebDewey.

Learning objectives for this session include
  • Learn the structure of Dewey Decimal Classification
  • Understand number building using DDC
  • Build DDC numbers for a variety of resources


Homework Expectations

  • Participants will need access to WebDewey or a print copy of Dewey to complete the homework assignment.
