Organization
The Colon Classification uses 42 main classes that are combined with other letters, numbers and marks in a manner resembling the Library of Congress Classification to sort a publication.
Facets
CC uses five primary categories, or facets to further specify the sorting of a publication collectively called 'PMEST'.
- , [[personality]]
- ; [[matter]] or property
- : [[energy]]
- . [[space]]
- ' [[time]]
Classes
The following are the main classes of CC, with some subclasses, the main method used to sort the subclass using the PMEST scheme and examples showing application of PMEST.

Example
The most commonly cited example of the Colon Classification is the classification for:
- "Research in the cure of the tuberculosis of lungs by x-ray conducted in India in 1950s":
- Main classification is Medicine
- (Medicine)
- Within Medicine, the Lungs are the main concern
- (Medicine,Lungs)
- The property of the Lungs is that they are afflicted with Tuberculosis
- (Medicine,Lungs;Tuberculosis)
- The Tuberculosis is being performed (:) on, that is the intent is to cure (Treatment)
- (Medicine,Lungs;Tuberculosis:Treatment)
- The matter that we are treating the Tuberculosis with are X-Rays
- (Medicine,Lungs;Tuberculosis:Treatment;X-ray)
- And this discussion of treatment is regarding the Research phase
- (Medicine,Lungs;Tuberculosis:Treatment;X-ray:Research)
- This Research is performed within a geographical space (.) namely India
- (Medicine,Lungs;Tuberculosis:Treatment;X-ray:Research.India)
- During the time (') of 1950
- (Medicine,Lungs;Tuberculosis:Treatment;X-ray:Research.India'1950)
- And translating into the codes listed for each subject and facet the classification becomes
- L,45;421:6;253:f.44'N5
