BibliOdyssey is a new and spectacular compendium of the printed image. From detailed posts on Rare Books of the Japanese Diet Library to a look at some strange illustrations for The Master and the Margarita, the site has a broad range and an eclectic composition authorized by the quality of the posts. Other highlights include Micrographia, a mysterious Astronomické České, the prints of Jacques Callot, and images from Sydney Parkinson's journal of his explorations of New Zealand and Australia. Be sure to look through the archives.
