There is a good description of Kokopelli in a book review in the Journal of Folklore Research: http://www.indiana.edu/~jofr/review.php?id=109
There also is a good article about Kokopelli: "Misconception, mystery shroud frisky Kokopelli" by Leon Drouin Keith, Arizona Daily Star, July 4, 1998, Page 1B.
