'One Hundred Best Books' is an essay where the author lays out his opinions on what he thinks is the best 100 books of all-time were, at the time when he was writing, which was in 1916. Some of the books that he included were downright controversial at the time, but are now widely celebrated, such as 'Alice in Wonderland' and 'Leaves of Grass'. Others, however, are books that were great then, and continue to be considered so now, such as 'The Odyssey', 'Faust', 'The Divine Comedy', and the poems of Walt Whitman.
