Hyperbolic perhaps, but above all the books on my shelves, this one has proved its value with the most consistency. I never tire of taking it down, and once I do it wont leave my bedside for months. Here is collected Yeats' entire published output, or damn close, and not only that, the second half of the book is given over to exegetic, detailed notes on each poem, which includes everything from explanations of allusions to interesting analyses, autobiography and socio-cultural context. The typeface is wonderfully clear, and the solidity of the hardback binding makes it even more perfect. Alongside my Allen Ginsberg 'life's-work' collection, this is possibly the best book of poetry I have ever bought.
