The poetry is, of course, deeply moving, haunting, wistful and beautiful. However, this Penguin edition was first published in 1956. You'd have thought they could be bothered to overhaul it with a check of textual accuracy and a new intro for the 21st century.
Maybe a new edition is in the pipeline. In the meantime save a few quid by getting the far superior Wordsworth edition. Also highly recommended are Wordsworth's complete editions of Hardy and Kipling, two other major poets whose work they do full justice to, unlike the bigger publishing houses.
