These are some of the books I wish I could own, often available used through places like Abe, Alibris, and Amazon, but are just too darn expensive.
American Magus Harry Smith: A Modern Alchemist, edited by Paola Igliori
The book I know of that is a comprehensive look at the life and work of this remarkable character; a music archivist, filmmaker, magician. Much of his work can be seen online, and in particular YouTube has a substantial number of his films.
I have seen this book for about $50.00-120.00.
One of the most comprehensive looks at the history of automata and the relationship to watchmaking. A beautiful massively illustrated volume. A book I have wanted for years.
Volumes in good condition are around $195.00- 300.00
