With millions of user-submitted reviews powering its advanced book recommendations engine, Goodreads can help you discover your next favourite—and keep track of what you’ve read.

What we love: Contributing to Goodreads’ huge community of fellow book lovers by sharing reviews, curating lists, and participating in book clubs—and getting spot-on suggestions based on our ratings. Reading Challenges keep us motivated—and we look forward to the Year in Books wrap-up, which summarizes all our stats.

Quick tip: Have physical books you want to rate, review, and share? Use the handy scan feature to import them using the camera on your iPhone or iPad.

Meet the creator: Otis and Elizabeth Chandler launched the online community Goodreads in 2007 to help people see what their friends were reading and share thoughts on those books.
