Avid readers enjoy immersing themselves in a great story and then discussing the book with friends and other book lovers. From book clubs to reading groups, reading has always had a social element, and now social media is playing a role.

Book-themed social networks and digital groups are becoming increasingly popular, allowing participants to share good books, discuss great stories, and review the latest bestsellers. Here are six great book-themed social networks for avid readers to check out.

The goal of Goodreads is to help users find great books to read by suggesting new books based on titles they’ve already read or what their friends are reading. It also focuses on helping readers avoid books that just aren’t right for them.

Goodreads lets you list your books, rate and review books, and discover what your friends are reading. Community features include a wide variety of groups to join, as well as discussions and an Ask the Author feature.
