The DDC

The NLB libraries employs the Dewey Decimal Classification system (or DDC) and partial application (i.e. first three letters of the author’s surname) of the Cutter Expansive Classification system (or Cutter system) for Non-fiction works, and the partial application of the Cutter System for fiction works.

The DDC (source: Wikipedia, Mar 2006):
The system is made up of ten main categories, each divided into 10 sub-categories, with each sub-category having 10 sub-divisions of its own. Only the first 2 levels are listed here.
