Learning SuDocs Call Numbers

This tutorial is designed to teach staff or student workers the SuDocs classification or call number system.  The first section, SuDocs Basics, gives a brief overview of the system and focuses on the three most important things to remember. The second section is an interactive quiz with multiple choice and true/false questions, where even wrong answers teach a lesson. In the third section, you can arrange call numbers in shelving order in four different call number sequences.
