The Official Preppy Handbook (1980) is a tongue-in-cheek humor reference guide co-written and edited by Lisa Birnbach. It describes an aspect of North American culture she styles as prepdom. In addition to insights on prep school and university life at socially acceptable schools, it illuminates many aspects of upper-class, old money WASP society. Topics range from appropriate clothing for various social events to how to choose the correct college and major. While the book addresses "preppy" life from birth to old age, its coverage is in the greatest depth for the school, college, and young-adult years; coverage becomes thinner for subsequent stages of life.
