I have been trying to buy this book for more than 2 years. Each time the publication date arrives Amazon moves it 3 months into the future. I have written to Amazon, Harper Collins (the US publishers) even the author himself. To its credit Amazon UK replied but told me nothing remotely helpful. The publishers and the author just didn't bother to reply. I only learned something useful when another reader started a discussion in which he sent me a link to an article in the New York Times saying that Mr Zinsser, now in his 90s, has gone blind. Since the 30th anniversary edition came out in 2006, the 35th anniversary edition should have been due in 2011, and we are still waiting. I have tried to bring this to the attention of Amazon but nobody is interested. Seriously, forget it - this book is a myth!
