Reddit is a social media and news aggregation website that ranks content based on a voting system. People worldwide post content (usually links, but also original content), and other users can “upvote” or “downvote” posts, pushing the most interesting content to the top. 

It’s a place where you can find groups of like-minded people. Reddit calls these groups subreddits, and they cover different topics, including niche interests, politics, hobbies, and thousands of other topics people want to talk about.

Since its launch in 2005, the site has become one of the most popular social media sites with millions of monthly active users. 

We've processed billions of comments to find the books most mentioned on Reddit.

Our methodology

Book mentions are found by checking every reddit comment for links to Amazon, Goodreads, Google Books, and O'Rielly Media. Non-link mentions are too tricky to parse in an unbiased way: books with short, simple titles like The Road get massively under- or over-counted.

When a user mentions the same book multiple times in the same subreddit, we only count the top-voted comment. This curbs users shilling a particular book, and gives a more representative feel for an entire subreddit.
