Introduction to Classification

  • Cataloging
  • Webinar
  • 1 CE Hour


Classification is the process of assigning a number to an item so as to be able to shelve the item with other items on the same subject. Along with subject analysis, classification systems help us keep our materials organized for the communities we serve. No matter what type of environment you work in—academic, school, or public—or whether you work behind the scenes creating records or in a forward-facing role assisting users, you can benefit from a better understanding of where to find classification information in MARC records, how they relate to subject headings, and where to go for more information on both Dewey Decimal and Library of Congress systems.  

Attendees of this session will have the opportunity to… 

  • Briefly review key vocabulary related to subject headings 
  • Explore how subject headings and call numbers overlap 
  • Learn where to find classification information in MARC records 
  • Discuss useful tools and resources for more information 


Participants should review the following entries in the Training Archive ahead of this presentation.
