The two that I've got are his "The making of landscape photographs" and "Seeing landscapes". The first one was published 1992 and the second 1999. Both seem to still be available on Amazon UK at GBP 9. They're both good books, the second is slightly more modern, better paper etc. They both deal with his thinking behind his photos for example, why he often uses 6x6. Sometimes he has several versions of the same photo taken at different times, slightly different angles etc, and he explains why one "worked" and the other didn't. Also, he's not afraid to crop if he feels the image needs it. Both recommended.
