Though MSU Libraries remain closed to the public due to COVID-19, we are preparing to welcome students this fall, and we are working on changes inside our Library to welcome people safely. Our goal is to reopen to the public August 24. Until then (and after), we will continue to offer virtual services. Many resources remain available. Please see our Online and Distance Learning resource page for specific Library resources. Reference services are still available via chat and phone. We do have temporary policies for returning/renewing material.

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.
