Some time ago I purchased several of the Perseus collections, when they were free. They are wonderful resource sets, but wow there are a lot of them, and they tend to pop up when I'm trying to do unrelated things with Logos. "Hiding" them isn't really an option because there are thousands of them and apparently you can only "hide" books one at a time- not by a collection or search. And besides, there are times I want to use them.
So how can I create a collection that is everything except my Perseus items? I can create a Perseus collection, and I see I can drop a collection I have into the "minus these resources" part of creating a collection, but the part I don't know how to do is to start a collection that by default includes everything, so that I can then put the Perseus books in the "Minus these" section and have a "Not Perseus" collection.
Thanks!
