To some degree, yes! The catalogs had only small snippets of most of the stories, but I expect most of them are in his seed database. He's mostly out of the business now -- he sold the company -- and I believe he's working on deaccessioning most of his seed bank to good homes and in the process is probably running across a lot of these stories. Perhaps they'll end up collected in a book.

(I'll DM you with more details, as I try to keep my account disconnected from name searches, if not entirely anonymous.)
