The term Generation X has been used at various times throughout history to describe alienated youth. In the 1950s, Hungarian photographer Robert Capa used Generation X as the title for a photo-essay about young men and women growing up immediately following the Second World War. In 1976, English musician Billy Idol used the moniker as the name for a punk rock band.
An atlas is defined as a collection of various maps of the Earth or a specific region of the Earth such as the United States or Europe.
A travel atlas is usually packaged for easy use during a trip, often with spiral bindings so it can be folded flat, and with maps at a large zoom so that they can be easily consulted on the go. A desk atlas features sizes and bindings that are typical for reference books: usually a paperback or hardcover format.
