What is a Typology?

A typology is the study and classification of things according to their characteristics. Things can be organised in many different ways, for example by their usage or function; by shape or colour; alphabetically by name; chronologically by age; or by location where they originate. The information design evangelist, Richard Saul Wurman, coined the term LATCH (Location, Alphabet, Time, Category and Hierarchy) to describe the ways in which things can be ordered.
