one version of the 12 volumes of The History of Middle Earth? I don't understand why it's so hard to find all volumes in the same format... some I'm finding in the mass-market paperbacks (which I don't want), then in the next higher quality paperback and a few I can only find in hardcover. Of course each is a different size, but I want something that looks like one set (and is one set)! Also, I've seen on Amazon and Borders Books how there are several out of print. This seems strange to me with the popularity of Tolkien! I would appreciate it if anyone has a source where I can get one complete set. Thanks.
