BookSuggester

I own or have read...

Unsuggester takes "people who like this also like that" and turns it on its head. It analyzes the ninety million books LibraryThing members have recorded as owned or read, and comes back with books least likely to share a library with the book you suggest. The unsuggestions come from LibraryThing data, not from Amazon. LibraryThing also produces great suggestions.
