Magic in Middle Earth (Help RPGers!)

[Horn, John]

I may have posted before that I am trying to design a fantasy role-playing
game campaign based on the Lord of the Rings.  I really don't like the way
the Middle Earth Role-Playing Game handles magic.  There's just too much of
it.  So I'm trying to do it myself but I'm really struggling with how to
define magic in Middle Earth.  I know there are others on this list who love
Tolkien as much as I do.    I was wondering if there was anyone here who
could possibly help me with this or could point me to some web resources
that might help.
