This page will list some useful resources to learn more about fan-culture history.
Fan-culture has a far longer and more colorful history than you might imagine. From fansites created at the dawn of the internet, to the printed mail-order zines that fans used to share fiction and art with before the Web was created, to even the fan-cultures that existed before the contemporary era, such as the one that arose from the massive popularity of the Sherlock Holmes series of books, these articles, videos, and books will teach you all about how fan-culture started, grew, and evolved.
For recent history and events, I recommend that you look through some of the links in the previous pages, such as the Fanlore wiki, the Know Your Meme wiki, and various community wikis located within various Reddit communities.
