Typographic Systems
Systems of typography are defined so as to expand from the visual and material dimensions and to encompass dimensions which are relational and operational - what people do and how they function (in the broadest sense).
An expanded definition can therefore draw upon the entire complex of practices, conventions, materials, technologies, social relationships, and institutional frameworks that organise visible language within any particular context.
So, a typographic system for administration or bureaucratic contexts would include the documentation used, their formats, the systems within which they are filed, and the institutional practices which are used to maintain them.
