In preparation for a possible (seemingly down from “probable”) move, I’m trying to move all my CDs in huge binders, throwing away the jewel cases. Part of me wants to keep the booklets—but I know I’m not likely to ever even open the binder if the CD is already ripped.

Jewel cases are the worst, but I certainly wouldn’t get rid of the booklets. It doesn’t matter if you look at them only once in a blue moon. In fact, I’d be more inclined to throw away the discs themselves than the liner notes. As I’ve said before:
Years ago, I used to argue that, whenever you buy an album as a digital download, you should have the option of getting a copy of the liner notes or Digipak mailed to you.

@artkavanagh I'm slowly becoming convinced I should keep the CD booklets, even if they're in a separate binder. (Actually, a separate binder might be preferable, since I probably won't need the actual CDs.) And, I was always a little surprised that online music purchases so rarely include PDFs of those inserts; some hi-res purchases do, but not many.
