Do firms still use loose leaf filing services?

Hi, do firms still use loose leaf filling services for their subscriptions or is that now obsolete?

My recent experience of law firm practice in this regard is very limited. I'm not aware of any particular firms that continue to use loose-leaf filing services, but that doesn't mean they don't exist.

Law firms can be very conservative.

EDIT: if they are still being sold, presumably they are still being bought:
