I share a similar fascination/interest in unusual books. I am currently in the process of collecting all the books on Autogenic Training written in my native language. There is a formidable wealth of knowledge that would otherwise not even be lost, but never acknowledged. These books are out of print and can be found in online marketplaces or some bookstores that deal in used books. I'm not interested in first editions or collectibles at all, just the information in the book. Previously, my interest was in 19th century bodybuilding and strength training books, along with WWI special forces diaries. It certainly contributed to my enjoyment of life and a certain, unusual way of looking at things (although the direction of causality can go both ways).
