The Complete Works of Irish poet Oscar Wilde, which is published by Collins, is a must for a private library. It is an excellent book even if you only want to check one of Wilde's witty quotes - and there are plenty. The book includes Wilde's only novel, The Picture of Dorian Gray, which caused a fin-de-siecle scandal about a century ago because of its underlying homoeroticism. There are also all his famous plays which he wrote and was loved for by English society such as The Importance of Being Earnest, An Ideal Husband as well as Lady Windermere's Fan. In addition, there are stories, poems (such as The Ballad of Reading Gaol - the jail he had to go to for his affair with Bosie Douglas), essays, and letters such as De Profundis. This newly illustrated centenary edition also incorporates recent revisions to the text, which probably only experts will spot.
