At 14.5 million subscribers, /r/Books is Reddit's 20th largest subreddit. We thought it would be interesting to analyze the subreddit's favorite authors and books, as a means to "encourage discussion about developments in the book world."

Approach

We scraped /r/books top 1,000 post titles, and then ran a frequency count for the world's most popular authors and books (similar to what laterforreddit has done for the subreddit's popular words and bi-grams).

For every book and book series we built a library of alternate titles — for instance, HP for Harry Potter, LoTR for Lord of the Rings, or GoT for Game of Thrones.
