Très Grande Bibliothèque, OMA's 1989 project for a national library in Paris, is being exhumed from the archive for an exhibition at the Canadian Centre for Architecture (CCA) in Montreal. The exhibition, curated by Rem Koolhaas and Clément Blanchet, presents models, drawings and research produced by OMA in response to an international competition launched by France's then president, François Mitterrand. OMA's design was for a giant cube with areas of emptiness that would accommodate the library's various functions - a "strategy of the void".
