'Self-Institution/Terminology Audit' is a collection of profiles and lexicons documenting artistic practices that operate as self-declared institutions. It examines the act of self-institution as both a conceptual and operational approach, focusing on how these practices structure themselves and engage with their contexts. Initiated by the Office for Joint Administrative Intelligence (O.J.A.I.), this publication investigates artist offices, bureaus, departments, ministries, societies, centres, and other explicitly institutional invocations. The Terminology Audit reveals language and jargon unique to each practice. The case studies, currently active in the field, represent a broad range of approaches, including research-based, performance-driven, pragmatic, materially motivated, counter-institutional, esoteric, and absurd facsimiles of institutionhood.
