Goodreads is arguably the leading online community for book lovers. If you want some inspiration for which book to read next, this is the site to visit.

There's an endless number of user-generated reading lists to explore, and Goodreads itself publishes dozens of "best of" lists across a number of categories. You can also join book discussions and reading groups with thousands of members.

You can participate in the community by adding your own rankings to books you've read and leaving reviews for other people to check out. Occasionally, there are even bonus events like question and answer session with authors.
