Beginning in 2003, the Theatre Archive Project is a major reinvestigation of British theatre history between 1945 and 1968, from the perspectives of both the members of the audience and those working in the theatre at the time. It encompasses both the post-war theatre archives held by the British Library, and also their post-1968 scripts collection. In addition, many oral history interviews have been carried out with visitors and theatre practitioners. The Project began at the University of Sheffield and later transferred to De Montfort University.
