On the lower level, piles of non-fiction books were quickly sorted into stacks by 000’s, 100’s, 200’s, etc. and then moved onto shelves, with no sub-arranging. This continued with all the books of fiction were sorted alphabetically from A to Z by author’s last name; then, onto shelves they went. Ditto with biographies, sorted and then shelved by subject’s last name. Meanwhile, other workers were working on the Easy books in the small room.
