The Compendium series is largely influenced by the vast history of artists working with instruction and scoring. In summer 2022, Reas started a new version of the Process Compendium series– a tribute to performances and drawing. Titled Process Compendium (X-N), the “N” is a number 4-18 for each 1/1 artwork in the series. Specifically, each artwork in the Process series is a set of instructions written in English before those instructions are translated into computer code. The works in Process Compendium stem from Casey Reas’ most iconic Process series dating from 2004–-2010. The Software Structures online commission from the Whitney Museum of American Art in 2004 was the origin of this work, and it was exhibited in Programmed: Rules, Codes, and Choreographies in Art, 1965–2018 at the museum alongside work by artists, such as Sol LeWitt, Joseph Albers, and Lillian Schwartz, all essential influences on his work.
