I'm not too Knowledgeable about LotR compared to some, but I got a lot of my information from the Tolkien Bestiary by David Day. It basically has a short summary (well, not always short, but you get the meaning) about basically everything in Middle-earth. Like he has summaries and pages about Sindarin, Silvan, and some other elves that I had never heard of before. He has write ups about the valar and maiar (even has some specific persons, I think). There are some pretty...ugly pictures in there, but on the whole, I think it is worth buying since it also gives sketcy history details and so forth.

I'm sorry I can't recommend anything more than this since that's all I've read -- except for LotR a thousand or so times... [img]smilies/wink.gif[/img]
