Hello,
For those of interested in Japanese Woodblock prints and a history of the floating worlds of Yoshiwara, the Library of Congress has a website that focuses on providing their collection of images of this unique period of Japanese history. The website offers a variety of woodblock prints, as well as brief histories of what these images would have meant during the period of time. It also provides some interesting images from the Japanese POV (point of view) in how they viewed their western visitors. As a whole, the strength of the website lies in its visual images (woodblocks) that most certainly can be used to help understand the art and history of this period.
