This came up on another forum, and I thought the topic was interesting enough to repost here. What works of literature do you consider essential to your library? Mine are Dickens' complete works, and some children's literature: The Secret Garden, Heidi, and E. Nesbit's Mouldiwarp Chronicles. Also Harper Lee's To Kill a Mockingbird. I have the Oxford Illustrated Dickens, and leather bound editions of all of the others, except the Mouldiwarp Chronicles, which was only available in hardcover. So what are your essential books?
