Here are some books I have found about the history and uses of labyrinths. Some have really nice pictures:
Labyrinths Ancient Paths of Wisdom and Peace
Secrets of the Maze: An Interactive Guide to the World's Most Amazing Mazes (I really like this one. It discusses the differences between labyrinths and mazes. And has great pictures of both.)
The Unending Mystery: A Journey Through Labyrinths and Mazes (This is more text, less pictures. Full of information
I created a Santa Rosa Labyrinth © (designed by Lea Goode-Harris) in my back yard in 2006 with the help of my son and two girlfriends (one toted rocks, the other talked me through toting rocks). My teenager did the lion's share of rock moving. My husband did the greater part of the mowing and weed eating. In Spring of 2010, my patient husband had the whole thing mulched and we replaced the rocks. It is available for walking by anyone in the area who needs the use of the space.
