No art history student can get through a semester without the twin doorstops of Art Through the Ages. Chronicling the history of art from the earliest known cave paintings to postmodern architecture, as well as most major artists, works, and styles in between, these books are must-haves for those interested in understanding art in context. Both books are surveys, and experts may notice the omission of more esoteric movements and artists. Regardless, these volumes are invaluable references--especially since each edition of this classic improves noticeably in its coverage of non-Western art.
