Sir, - As I have been commissioned by Messrs Gill and Macmillan Ltd to write a biography of Sean O'Casey (1880-1964), I should like to appeal to any of your readers who may have unpublished material and/or memorabilia to get in touch with me. All such materials will be carefully photocopied and promptly returned, and acknowledgement will be supplied in the published text of the book in due course. - Yours etc.,
