Do not waste your money on any version of JE Taylors Tolkien books. He hides his "references" at the back of the book instead of professionally citing them on the page for the entry you are reading. If you are a Tolkien purist you will find many fictional made up details in this book. Instead buy the book that Christopher Tolkien himself cites...Robert Foster's Complete Guide to Middle Earth. This book is VERY accurate for your Hobbit,LOTR, Simarillion reference needs.If you need a cross-reference for the 12 volumes of the History of Middle Earth buy Christopher Tolkiens Index to the History of Middle Earth. You can buy that at Amazon UK.
