All of the Books
Here is a neat thing from Hacker News: A visualization of every ISBN made, displayed as a massive bookshelf.
ISBN’s are assigned to printed publications, and as an international system you see them on pretty much every book you’ve ever looked at. You can use the tools in this project to search for a specific title, or browse endlessly.
This project was submitted as part of a contest for Anna’s Archive. You can see more submissions there.
