WorldCat Genres

"WorldCat Genres allows you to browse dozens of genres for hundreds of titles, authors, subjects, characters, locations, and more, ranked by popularity in the world's libraries. It is a joint experiment from OCLC Research and the WorldCat.org team. As an experiment, expect it to evolve and grow over time. We hope you find it valuable and invite you to offer feedback (at the bottom of every page) on what you like, what you don't like, and what more you'd like to see"
