"Yeats Annual" is an established research-level publication for current thought and documentation upon the life and work of "the greatest poet in the English tongue of this century" (Dame Helen Gardner). The focus in this sixth number is on Yeats at work on various manuscripts and on his tours of America. Almost every contributor draws on unpublished material and the items contained in this work included the complete surviving archive of letters to Yeats from Olivia Shakespear published for the first time, the earliest surviving manuscripts of "Cathleen ni Houlihan" by Lady Gregory and Yeats, an examination of the manuscripts of "Deirdre" and Yeats' interest in Arthurianism, plus an account of his first tour of California in 1904 and a re-examination of several of Yeats' works such as "Responsiblities". The volume also includes a number of reviews on works written about Yeats.
