YEATS 150 is a collection of essays, many of them illustrated, commemorating the life and work of Irish poet and Nobel Laureate, William Butler Yeats (1865-1939). The book, dedicated to Seamus Heaney, is divided into a number of sections: Academic Essays; Plays; the Yeats family; Scholarly Essays; Yeats Poetry Prizes and, appropriately, the topographical ‘Sligo’, by Sligo natives and visitors to the International Yeats Summer School.
