Thanks. I remember looking into this a while back and finding some of these limitations. Maybe it’s time to try again, as much as I’m not a fan of paying a subscription
My kids are in a similar spot and I can’t recommend teaching them the power of asking a (real) librarian at a (real) library enough, if that’s something that’s possible for you. Those folks are special and my kids love wandering through the children’s non-fiction a few times a week.
