about

Cooper Hewitt’s permanent collection includes more than 215,000 objects, which span thirty centuries and a wide variety of materials. The Conservation Department cares for and studies these pieces to ensure their preservation for today and into the future. Conservators provide expertise in the conservation of works on paper, textiles, and three-dimensional objects made of media ranging from brittle glass to pliable plastic. Sarah Barack, Head of Conservation and Senior Objects Conservator, offers a further introduction to the department.
