Thank you for sharing my site! I built this a number of years ago as I was starting to learn about Japanese prints. I wanted a single place where I could find them across all of the various museums and universities that hold them. I use computer vision analysis to cluster prints together (using TinEye). A bunch more technical details from the last time this was posted: https://news.ycombinator.com/item?id=18344979

I’m working on a new site now that’s focused on prints that are for sale from dealers and auctions. Much more technically complex as it needs to be continuously updated. Hope to have a public beta soon!
