A reference guide of typographic terms and classification with definitions of form and usage for Latin-based writing systems, the Typographic Desk Reference (TDR) is an encyclopedia listing countless entries on the typographic arts. Glyphic has editted, written, and designed the TDR from 2007 to 2016 across two editions issued by Oak Knoll Press. The TDR continues to be well received in the type and design industries, and is used in most universities that teach graphic design.
