I’ve seen this once or twice but barring knowing the goal of the owner wasn’t sure if it’s appropriate to help restock.

As a big example I believe many of these are lgbtq or diversity friendly but that can be controversial. It’s not my business to make a statement in your library: should I donate an lgbtq book? a western? Romantic? Children’s? I have them all and support almost any goal encouraging reading or thinking, i just need to know what it is
