When Jonas initially enters the Annex to begin his training session, he is astonished to discover the Giver's extensive book collection. Jonas mentions that in his own dwelling, there are only a few "reference volumes," which include a dictionary, a community volume, and a Book of Rules. In the community volume, there is a description of every building, office, factory, and committee in the community. Jonas is only familiar with the several books in his dwelling and had never known any other books existed. Since Jonas's community is founded on Sameness, individuality is suppressed and literature is tightly regulated. The dictionary is a particularly significant book because the community places such importance on specific language. The Book of Rules is also significant in Jonas's community given the highly regulated nature of his society. Unlike the rest of the community, the Giver has access to any type of literature and possesses historically relevant books, which contribute to his wisdom and understanding.
