The list author says: "These are books that all parents should have in their home. They are books that make a great foundation for future learning- beginning books encompassing a wide range of subjects from philosophy to anatomy to architecture.
Most of these books are in the 4 to 8 year old age range but are meant really for any range group. They are jumping off points- from which a child can choose to explore topics that interest him further- by getting more detailed books out of the library or from the bookstore.
Whenever possible I've chosen richly illustrated color texts to help aid in the visual learning experience."
