Ace of Stars, there was a thread running about this subject not too terribly long ago that you might want to check out
here. I wrote little entries about a few of the Rune books in my collection, and a few other people chipped in some of their thoughts on the subject, too, so it might be helpful for you to take a look (it's not too long, either).
I echo Aeric's praise for Tara Hill's site -- that's actually where I got my own Runes, and the meanings section there really helped to get me started when I began my studies in this area.
I'm also with magpie9 in liking Diana Paxson's
Taking Up The Runes. I haven't actually read it through, cover to cover, but the more I dip into it, the more I'm appreciating it. I wrote a bit about it in that other thread.
Also, several of us have been doing a Rune Reading Exchange in which we read for each other. This month, instead of sticking to set spreads as we probably would if reading with Tarot or other Oracle cards, we're adding in the possible choice of doing an actual Runecast. Should be a lot of fun, and very educational! Please feel invited to participate, or if you don't feel ready for that just yet, it still might be helpful to just follow along as we read for each other and give feedback. The thread for the April RRE is
here.
I hope this was of some help to you!
