I am reading Stuart Kelly's The Book of Lost Books: An Incomplete History of All the Great Books You'll Never Read and thoroughly enjoying it. I am afraid we do not have a copy in the Olin Library, but it is at the Winter Park Public Library, though checked out at the moment. It consists of many short chapters, each one about an author who wrote at least one work that is lost, no copies are known to exist, was never written, or not finished . It is fascinating, funny, heart breaking, and thought provoking.
You can imagine what a horribly delicious read this is for a librarian.
