Books of the Century is derived from an exhibition currently on view at the New York Public Library in which both Research and Branch librarians identified books from their collections which helped to define the last 100 years (1895 to 1995). The books they chose range from ones that influenced history, such as Adolf Hitler's Mein Kampf, to books that entertained millions, such as Dr Seuss' Cat in the Hat. A passage devoted to each book describes its content and signficance to the past century.
