hyman's bookstore started a book registry in the late 1940s, so that there would be no duplication in bar mitvah gifts. another one of hyman's specialties was office supplies. in addition, the business was renowned for its jewish greeting cards sold during major jewish holidays. many jewish "landsmanshaften" [organizations of people from the same european area] depended on hyman's service for mimeographing multiple copies of local community society newsletters and minutes.
