Mad Norwegian Press is an American publisher of science-fiction guides and novels. Mad Norwegian was founded by Lars Pearson, a former staffer at Wizard Magazine, and is based in Des Moines, Iowa.
The majority of the company’s output is reference guides to science-fiction series such as Doctor Who, Buffy the Vampire Slayer, Angel and The X-Files. As a rule of thumb, such guides examine the continuity that governs each show – taking into consideration how different episodes reconcile against each other, for instance – along with critiques, theorizing and behind-the-scenes details. The “About Time” series, a series of guidebooks to Doctor Who, deviates from this formula somewhat by examining the political and cultural context (as well as the development of television) that influenced Doctor Who on a year-by-year basis during its initial 26-year run (from 1963 to 1989).
