The Sketchbook Project
The Sketchbook Project is a crowd-funded sketchbook museum and community space based in the Brooklyn Art Library. So far the museum has over 35,000 sketchbooks contributed by artists from over 135 countries and all of these books can be seen at the library where the collection is exhibited.
I first contributed a sketchbook to the project in 2011 - pages of which can be seen below.

There is also a digital version of the library which contains thousands of the sketchbooks digitally scanned in. Have a browse here: https://www.sketchbookproject.com/library
