Goodreads is a free website for book lovers. Imagine it as a large library that you can wander through and see everyone's bookshelves, their reviews, and their ratings. You can also post your own reviews and catalog what you have read, are currently reading, and plan to read in the future. Don’t stop there – join a discussion group, start a book club, contact an author, and even post your own writing.
