The Sackler building, which was originally designed as an extension to the Fogg Museum, elicited worldwide attention from the time of Harvard's commission of Stirling to design the building, following a selection process that evaluated more than 70 architects.[30][31] The university mounted an exhibition of the architects' preliminary design drawings in 1981 (James Stirling's Design to Expand the Fogg Museum), and issued a portfolio of Stirling's drawings to the press.[citation needed]
