Withholding: a reading room for the Archive of Constraint is a temporary site for study; a resting space within and among the undercommons, it is an active performance of refusal and fugitive planning. Drawn from objects and ephemera held within the Archive, this project traces the ongoing legacies of carceral systems from colonial occupations and their image-making practices. Primarily devoted to materials made during US imperialism in the Philippines following the Spanish American War, the materials held in the Archive of Constraint highlight the precarious nature of objects bought and sold online via auction sites and antique retailers. Held in tenuous suspension apart from larger institutional archives, these objects are often devoid of any historical context that a seller may offer if any is offered at all. Gesturing to a kind of annex, these online retailers store these objects off-site (in their collections elsewhere) while portions of their materials and information are available on the web, made completely available for viewing only after purchase. Within this context, Withholding is therefore an expanded, experimental site of performance whose relics are composed of objects, videos, and images sourced from within the Archive. Mapping the contours of corporeal colonization found throughout vernacular images and ephemera of colonial material culture, the work of and inside the reading room thus linger on two central questions: how do we outline the conditions of looking? and further, what are the edges of possession (and sovereignty) in the aftermath of colonial extraction?
