I don't know status of JH library but when it's open you can drop off unwanted books. You go into the stairwell on your right when you enter and there are bins under the stairs. Also the local Salvation Army, open only fleetingly even in the best of circumstances, takes used books, in my experience. I think you have to get there in the morning or after 5 pm, but you can call them. And again, I don't know if they are open under the circumstances.
