This map offers an alternative way to browse the 2,619,833 images contained in the Internet Archive's book collection. It shows 5500 different subjects which have been algorithmically arranged by their thematic relationships. The size of each link resembles the amount of images that are available for that topic. Clicking on a link will open the flickr page containing all the pictures for that subject. Rolling over a link will highlight all the topics that have a direct link with the subject.

The map can be dragged with your mouse and you can zoom in and out using the mouse wheel or multi-touch gestures. You can also use your browser's search box to find and highlight topics you are interested in (press CTRL-F on your keyboard to open it).
