One approach I've seen people take is to get non-resident library cards to large library systems like the NY Public Library or the Chicago Library. You can put multiple library cards into Overdrive/Libby/whatever and then you can see availability for all the valid cards you have.

And isn't this "available digital copy" issue at the heart of the lawsuit the Internet Archives is dealing with when they stopped placing copy limits on digital books at the start of the pandemic?
