Whether at the local library, online on facebook, or as a tv show, there are lots and lots of reading clubs. Tolkien belonged to one. Kids have their own. Academics have their own rules. Princeton even awarded Oprah an honorary doctorate in 2002, partly for her online reading club! Allegedly an idea at the Universities of Oxford and Cambridge, reading clubs are arranged by students for students. Though I guess this one at the Oxford University Press website is not that particular Oxford Reading Club
