The documentary reminders of Edward Gordon Craig's influence on the world of theatre are in museums and libraries all over the world, partly because he was such a prolific writer, but also because his genius and the personality that went with it were impossible to ignore. Almost every piece of paper that contains his work, whether in published form or manuscript, feels like a vital clue to the mystery of the man whose opinions about the role of theatre and art in society helped shape those worlds. Craig felt obliged by his own sense of importance to record his thoughts on paper, and his friends, family, correspondents, readers, critics, and reviewers have helped preserve his written legacy by saving those records, more of which become available to researchers every year.
