The first sets appeared in 2001, to coincide with the release of the first film "Harry Potter and the Philosopher's Stone" (Harry Potter and the Sorcerer's Stone in the United States).  Subsequent sets were released alongside the new films, until Harry Potter and the Order of the Phoenix.  The line then went dormant for three years.

The Magical Worlds of Harry Potter: A Treasury of Myths, Legends, and Fascinating Facts is a guide to the fictional "Harry Potter" universe, written by David Colbert.

Colbert conceived the idea for "The Magical Worlds of Harry Potter" while quizzing his nephew and nieces about the mythological references in the novels.  He later wrote the book while teaching a seminar on self-publishing to graduate students at the University of North Carolina.  The book was published in March 2001, without approval from Rowling, and has since received positive reviews from critics.
