I was incredibly excited to get a hardcover of this at a thrift store, in nearly brand new condition, for fifty cents. Why someone threw it away I have no idea.
And while it's a large selection and for the most part is very good, it has some issues, first and foremost, inconsistency in translations. Since the book has dozens of translators throughout, it's going to be hit and miss. Fortunately, it's mostly hit, but I was sad to see that "Ode to Enchanted Light," one of my favorite Neruda poems, was butchered in the translation. There are a few other duds throughout, translators who knew nothing of Neruda or his flow.
Some people have complained that it isn't side by side bilingual, but this isn't too much of a problem for me. While it would be nice, it would also cause the book to be over 2,000 pages, and it's already huge.
My final thought is that while it's not perfect, it's a good book. I certainly wouldn't pay $40 for it (the hardback cover price), but buying a paperback or a used hardback would be a good move for lovers of Neruda.
