What is the fate of a library book that never gets checked out? Does it stay in the library anyway, holding fast in its place, waiting for someone to borrow it? Or does it eventually get cast off, donated to a thrift or used bookstore or incorporated into the collection of a place like Brooklyn’s Reanimation Library? And what does it say about the book itself, that no one has ever wanted to borrow and read it? Is it a failure of its form?
