Another example of an enumerative classification scheme is Dewey Decimal Classification (DDC), also examined in depth in Chapter 2. DDC, however, possesses features that place it closer to faceted schemes on the continuum.
What are enumerative and faceted classification schemes?
An enumerative classification contains a full set of entries for all concepts. A faceted classification system uses a set of semantically cohesive categories that are combined as needed to create an expression of a concept. Many library classifications combine the enumerative and faceted classification techniques.
Is a best example of purely enumerative classification species?
