God, loads. I sometimes have a nice first edition, and a reading copy. From where I'm sitting I can see two copies of all three volumes of Rebecca West's The Fountain Overflows trilogy, two copies of Elizabeth Bowen's The Last September, two copies of an anthology of Irish fantasy writing, and two of Patrick Leigh Fermor's A Time of Gifts, one with bad water damage, which is why I think I bought another.
But there are loads more. For ten years I lived between two different countries, and my books were split between the two.
