Don't bother re Shade. I don't consider it 'canon,' and it's not really set even in the Loremaster milieu, much less Shadow World.
It's actually more about completing my collection of ICE books. I have all of the original RM/SW/MERP/SM books that I knew of back in the day, but there are a few I don't. I'm also looking to get mint or as near to mint copies off stuff that I used to run games back in the day and is no longer mint as a result. When you have 6 people thumbing through spell law every game night it takes it's toll on the books. The PDF's are great, because I can read them on tablet.
Now the hard copies all stay in protective covers, my precioussss!
I always do the hard/soft copy + pdf through RPGNow for that reason, and that combo for these releases is really appreciated.
