When Covid-19 closed galleries, libraries, archives and museums, what did we learn about their role? And how might a year of empty galleries, locked exhibitions and inaccessible collections transform the sector in the future? Now that so many archives are digitised, are these physical spaces and the collections they hold redundant? Join Xerxes Mazda, Head of Collections and Curation at the British Library, Louise Siddons, associate professor of art history at Oklahoma State University and a Fulbright Fellow at the Eccles Centre for American Studies at the British Library, and Charles Saumarez Smith, former Chief Executive of the Royal Academy of Arts and author of The Art Museum in Modern Times. They talk to Erica Wagner, author and critic, whose latest book is Chief Engineer, about the builder of the Brooklyn Bridge.
