You are the librarian for a small church meeting in the catacombs outside of Rome. You have been tasked with building a representative collection of manuscripts of the various books of the Bible. Unfortunately, you have limited storage space. Therefore, your goal is to complete a library of three books from each of seven categories. You need to keep the books in the canon order and you can’t move a book once you’ve placed it. Unfortunately, other churches are also trying to build their libraries.
