Steampunk Work

Paul Guinan’s Boilerplate, the biography of a robot in the late 19th century, began as a website that garnered international press coverage when people began believing that Photoshop images of the robot with historic personages were real. The site was adapted into an illustrated hardbound book Boilerplate: History’s Mechanical Marvel, and published by Abrams in October 2009. Because the story was not set in an alternate history, and in fact contained accurate information about the Victorian era, some booksellers referred to the tome as "historical steampunk".
Fantasy-world
Since the 1990s, the application of the steampunk label has expanded beyond works set in recognizable historical periods (usually the 19th century) to works set in fantasy worlds that rely heavily on steam- or spring-powered technology.
