Nice find. I have probably 98% of his stuff in hardcover or large size. The exception being the first 2 DT novels which I gave away and, years later, replaced them with 2 paperbacks. I have bought them over the years as they were released and gave a lot of of them away. It was about 5 years ago I decided to fill in the gaps and found a lot of his books at salvation army stores and used book sales and shops.
