But more affordable alternatives to campus bookstores have cropped up in recent years. The classic Russian novel Anna Karenina by Leo Tolstoy, which remains a staple on the reading lists of English courses, provides a powerful example. The Kenyon College bookstore lists Anna Karenina for $18.00. The online learning platform Chegg lets users rent the novel for $9.99 or buy a used copy for $4.99. And the volunteer effort Project Gutenberg and Google Books let users access the novel online for free. At first glance, Project Gutenberg and Google Books may seem like the best options because they're free. But Project Gutenberg only contains 49,000 older books whose copyrights have expired. And students will be frustrated to find that Google Books often leaves out several pages. In light of these limitations, Chegg emerges as a great choice for students in search of flexibility.
