Notes Universal classification systems that rely on synthesis (faceted systems)

• Bliss Bibliographic Classification
• Colon Classification
• Cutter Expansive Classification
• Universal Decimal Classification
Newer classification systems tend to use the principle of synthesis (combining codes from different
lists to represent the different attributes of a work) heavily, which is comparatively lacking in LC or
DDC.

Comparing Classification Systems
As a result of differences in notation, history, use of enumeration, hierarchy, facets, classification
systems can differ in the following ways:
• Type of Notation: Notation can be pure (consisting of only numerals, for example) or mixed
(consisting of letters, numerals, and other symbols).
• Expressiveness: This is the degree in which the notation can express relationship between
concepts or structure.
• Whether they support mnemonics: For example, the number 44 in DDC notation usually means
it concerns some aspect of France. For example, 598.0944 concerns “Birds in France”. The 09
signifies country code, and 44 represent France.
• Hospitality: The degree in which the system is able to accommodate new subjects.
• Brevity: Length of the notation to express the same concept.
• Speed of updates and degree of support: The best classification systems are constantly being
reviewed and improved.
The following qualities are important for assessing a classification system
Consistency
Simplicity
