Thanks! Yes, unfortunately the physical book was never released as an e-book. It was released around the time e-books were first becoming viable, and a few months after it was published the publisher proposed we release it as an e-book. But the new contract was very far-reaching, and would have granted the publisher half of all proceeds of any "electronic distribution" of the book's content. When I asked them to revise the contract to exempt the preexisting website from this condition, they lost interest.
