[meteorite-list] CAI and chondrules

[gracie]

Wow. Thanks for the heads up on that. As a new collector of meteorites
I've been routinely going to Wikipedia for information on things like the
the formation of chondrules and inclusions.

I own Norton's Field Guide and the recently published "The Fallen Sky".
What are the other definitive books and/or websites should I be hitting up
for ACCURATE information?

Thanks in advance!
Gracie
