NAME THAT BOOK: A collection of literary anagrams

This book contains 400 anagrams of book titles written by some of the world's best known authors. Some are classical, some are modern day, some are children's writers and one is a playwright. The first eighteen sections each contain 20 anagrams of books written by a single author. The final two sections are slightly different in that the first is a collection of works by seven famous female writers who have not written enough books for them to have their own section. The second is a random selection of well known titles from several authors. Both of these sections require you to identify both the books and their authors. In both sections the authors' initials have been given to aid in your quest.
