Fantasy is much older than Science Fiction and is also much closer to classic literature. The 100 books reviewed here make this quite clear.
Fantasy books by authors from classic literature includes works of Johnathan Swift, Edgar Allan Poe, Charles Dickens, Emily Bronte, Robert Louis Stevenson, Oscar Wilde, and Franz Kafka.
Fantasy books from familiar Fantasy authors include works of Tolkien, Mary Shelley, Lord Dunsany, William Morris, E.R. Burroughs, Fritz Lieber, Ursula K. LeGuin, and many others.
Each review tells about the author, the book, and its significance in Fantasy literature. This book is really an indispensible guide for Fantasy fans looking to find significant Fantasy literature from the earliest works to the contemporary.
The only major flaw in the book is the under-emphasis of Michael Morcook's works. Because Michael Moorcock is a co-author, the authors felt that his works should be de-emphasized as a matter of journalistic integrity. Too bad.
I think you will find this book much more helpful than Pringle's "Modern Fantasy" guide as Pringle's review only covers works since 1946--after so much of the world's innocence and romanticism had been lost.
