Provide quick reference guides that are user-friendly, beneficial, and offer a good value as an alternative or supplement of gaining knowledge in a wide variety of subjects. Despite their “quick reference” moniker, these charts are loaded with important information and crammed with full-color, detailed illustrations, all clearly delineated and defined. They are an indispensible student resource and can be used in the classroom as a memory refresher when reviewing prior to exams, or as a homework aide. Each is laminated for long use.
