About the Authors: The name Andy Adams was a pseudonym used by Grosset & Dunlap to conceal at least three different authors. All but volumes two and three of the series have been attributed to Walter Gibson, Edward Pastore, or Peter Harkins, all of whom had notable careers in addition to their work on this series.

About the Illustrators: While the Dutch editions are credited to Rein van Looy, and the Swedish covers were painted by Rickard Lüsch, the American, British, and Norwegian editions do not tell the names of the illustrators. Judging by art style, it appears there were at least two different illustrators who worked on the American series, but probably only one artist for the Norwegian books.

Find out the countries Biff has visited during in his adventures across five continents, and read about the friends he makes in each story who help him out of so many scrapes.
