The Internet Archive (archive.org) continues to be a fantastic source for public domain works of ancient manuscripts, complete with images of the cover, binding and the endpapers.
Continuing my research on the symbolism and graphic arts of alchemy recently turned up a score of books that have not been available before. Especially important is the personal papers of Manly Palmer Hall (March 18, 1901 -August 29, 1990) who founded the Philosophical Research Society in California.
The Manly Palmer Hall collection of alchemical manuscripts, 1500-1825 was transferred to The Getty Research Institute, containing 243 manuscripts on the subjects of alchemy, hermeticism, Rosicrucianism, and related arts bound together in 68 volumes. The first two endpaper samples on this page are from this collection. The second example is my favorite - with two marbling techniques on the same page.
