Right now the "similar books" thing is based on a "topic-model"...

So books are more likely to be similar if they're roughly in the same genre and discuss similar kinds of topics (dragons, computers, romance, spies, war, shopping, time-travel, magic, hunting, etc).

Someday I hope the "similar books" feature will be a bit more sophisticated, where other kinds of "similarity" will also be relevant, beyond just the topic-model... Other things like: story structure, narrative voice, irony, vocabulary, sense-of-humor, lyricisim, etc...
