I bet the Tesla books are interesting reads.

I'm still going thru the Forest Gardening book in bits and pieces. There is a ton of detail and charts in it to refer back to in future dates. I'm starting to work on a few notes as i go (and highlighting).

I just got a new book yesterday i have just started on as well. "Blacksmithing, Basics for the Homestead". After two chapters it appears that it is going to be a good reference book as well.
