Classification Depth

For the majority of items in our non-fiction collection, truncate the number at the first segmentation mark (indicated by a slash “/”) or at the fourth digit after the decimal point — whichever comes first.

In areas where we have particularly in-depth collections, use however many digits are needed to represent the specific topic matter covered in each text. Subject areas where you will often go beyond four digits include:

  • 64X: Cooking
  • 72X: Architecture
  • 74X: Graphic arts and decorative arts
  • 77X: Photography
  • 973: United States history

Tricky Areas

To simplify the shelving of spread-out topics, we’ve made some local decisions that may conflict with the Dewey numbers recorded in OCLC bib records. Watch the call numbers on pre-processed books covering these topics (details on assigning our numbers can be found in the individual tables on this site):

  • Family life (306 vs 646): parent-child relationships, marriage, divorce, etc.
  • Graphic design: general layout/design practices vs typography (font work)
  • Retirement:
