Wow! i have read tolkien books for many years but this brings up new and unexpected questions in a huge scale! If you think you know a lot then test your true worth this this amazing collection. A vast range of catagories allows for a great focus on topic specific areas aswell.
At first glance this little quiz book should be a gem for Tolkien fans, and indeed there is a lot of interesting stuff in it and some good quizzing.however as you start to use it you find two things. The first, that may make quizzers unhappy, is the unevenness of the question-levels even within single quizzes. Thus you can go straight from the most basic what-kind-of-creature-was-Gimli sort of question to the most abstruse aspects of Elvish genealogy from deep in the "Silmarillion". Quizzers who prefer that roughly the same level be kept throughout a given quiz will not be too happy.
I did find one definite mistake, we are told that Haradrim = Easterlings (Quiz 40, answers), when in fact they are Southrons (the correct answer was Easterlings). And in Quiz 20 answers we are told that Sam Gamgee is the father of Bilbo. Yes, he did name one of his many eventual offspring Bilbo but I fear a lot of the book's users will not know that "small print" fact and may well dismiss it as another error that casts doubt on the reliability of the whole book. That was a quirk too far. A pity, because the book is enjoyable.
