WikiMentions lets you discover books/people/videos mentioned by great people. It’s a graph of mentions where people mention other people/books/videos in books/videos. Also it’s a wiki so anyone can add content. We already have around 2200 books and 1250 videos of 980 people. You can add content without signing up. You only need to sign up to edit or delete something.

We are team of 2 working on this full time for the past 6 months. Feedback is highly appreciated. Thanks!
