Archive in the Works plays on the double sense of the archive as a site under construction and as a field continuously reshaped by the artworks that activate it. Through critical and aesthetic interventions that foreground the archive's negotiated character, archival art destabilises conventional ways of organising, preserving, and representing memory. In the Latin American context, these interventions engage collections shaped by histories of colonial extraction, displacement, and uneven regimes of inscription, where violence and silence remain structurally embedded. This volume brings together reflections and creative responses from the first Activation Lab, an experimental research and creation platform for Latin American artists working with archival materials.
