Sydney, I really recomend getting a book called 'Tolkien and the Lord of the Rings: A guide to Middle-Earth' by Colin Duriez. It's not so much about the history of Middle Earth, but it has an excellent section all about the people and places from the three ages. Kind of like a glossary. Really useful if theres a particular person or place you want some info about.
