The first corpus was created thanks to the data made available by Theatre Record, a magazine originally created by the English critic Ian Herbert. Theatre Record reprints in full all the national drama critics’ reviews of the latest productions in and out of London. Published every two weeks in England since January 1981, it is in January 2019 that its archives were digitized thanks to Julian Oddy. Each issue published by Theatre Record has the same structure. For each of the shows mentioned, a number of reviews as well as a series of information related to the production (cast, photographers, technicians, etc.) are given. The venues where the plays were performed (The Royal Court Theatre, The National Theatre, The Old Vic, etc.) as well as the opening and closing dates of the shows are also identified. The newspapers in which the reviews were published are known to everyone: The Times, The Guardian, The Independent, The Sun, The Observer, etc.
