This booklet was produced by the students and teaching team of MATTERS: Connecting Arts + Design to Materials, and Materials to Labor + Land. The terms it contains exist at the entangled intersections of material, land, labor, art, design, power and social/ecological justice. The definitions were co-written and edited by course participants and teaching team. Sources of specific knowledge and quotes are acknowledged, while "common knowledge" and general information are not specifically attributed. The definitions are not meant to be static or comprehensive, but representative of ever-evolving meaning and critical interpretation, and a relationship to this moment.
