The Complete Guide to Middle-earth
Originally published soon after the publication of The Silmarillion, it is generally recognised as excellent reference book on the subject. However, as it does not include info on post-Silmarillion material (i.e. Unfinished Tales and The History of Middle-earth series), in points it is in error.
