The first three images shown are from the wooden library at Alnarp, Sweden ~ there are 217 volumes in the set. This specific xylothek was made in Nurmburg, Germany from 1805-1810. Each book is made from the wood of a specific tree or shrub and contains specimens pertaining to that variety as well as a written description, biology, and practical use. What an amazing way to catalog ones research! Read more and see a few more images of the wooden library at Alnarp here.
I wasn't able to find very much information or images ~ just bits and pieces here and there, but I'll share what I found. Below is a similar xylothek to the one above ~ apparently the makers of the wooden library at Alnarp made multiple sets to sell, so this could have been one of the other sets.
