I was glad to see that whole wiki posting about nested collections. That really helped.
Now, my question is just a touch different: I would like to create a collection of every resource I have except my bibles.
Now obviously, I realize that in the "Minus these resources" field I'll throw in the collection I created called "Bibles only". The question is: how do I include all other resources in the in the "Start with" field. is there a type called "All" or anything like that? In other words, can I avoid having to drag about 1200 books over?! 
Come to think of it, is there a way to know what all the "types" are that are used in L4? That would at least be a start in cutting down how much dragging I'd have to do.
Hope my questions makes sense! Thanks kids!
