Westerville Public Library
The library has book club kits with eight or more copies of a book, a readers guide, and anything else that you would need to have a reading group. These can be put on hold and checked out so that everyone in the book club can have a copy of the book at once.
The library has audio players available for checkout so that patrons who use the online recorded books can have something to play them on.
