Named for Paul Otlet — a librarian and visionary who popularized the 3×5 index card catalog and whose work in the early 1900’s prefigured the Internet — Otlet’s Shelf is a project in the spirit of free information exchange.
Share a summer reading list. Keep track of the books on your physical shelves. Organize references around a subject of interest. Publish a wishlist. However you use it, Otlet’s Shelf is a simple tool which aims to turn the private act of collection into something shared.
