I have two copies of Patrick Fermor's A Time of Gifts. One is a cheap paperback, for reading in the bath, and the other is a beautiful hardback that I use sparingly.
I also have three copies of P. G. Wodehouse's Right Ho Jeeves. Again, one is a cheap paperback for reading in the bath. Another is also a paperback, but I like it and don't want to crease or damage the cover. I also have a hardback, which, again, I use sparingly.
I have two copies of Aldous Huxley's Chrome Yellow. Both are paperbacks, but I love the original paperback cover and can't find a replacement, not even on Amazon. So I use the other paperback with a rubbish cover and smaller print. I have loads of hardback copies of Aldous Huxley's novels and essays that I bought in a secondhand shop that was closing down, many of them first editions. Some of them are gorgeous. I even have three hardbacks of Huxley's novel Eyeless in Gaza. If I ever make a good friend who likes Huxley, I will gift them one or two of those copies.
I have two copies of Evelyn Waugh's Decline and Fall, and I have his Sword of Honour trilogy in both a single volume and as individual copies.
I have more than one edition of the same works by George Orwell, Dickens, Jane Austen and Douglas Adams. Oh, and I have three copies of Oscar Wilde's Dorian Gray. I got a problem I tell ya.
