The NASA website hosts an excellent Java-based application that models seven different types of kites and simulates their performance in various conditions. This is helpful information if you need to troubleshoot, modify, or develop a new design: http://www.grc.nasa.gov/WWW/K-12/airplane/kiteprog.html/.

“Diamonds in the Sky: The Contributions of William Abner Eddy to Kiting” is a great article about the father of the Eddy bow and includes information about Victorian kite mania (from a 1999 issue of Kitelife Magazine): http://best-breezes.squarespace.com/william-abner-eddy/.
