There is a very good introduction and demonstration of various multi-dimensional index structures (quad-trees and R-trees) at the following link http://www.cs.umd.edu/~brabec/quadtree/index.html. The applets may take a while to load.
You can find a more formal description of multi-dimensional index structures at the following URL http://wwwipd.ira.uka.de/~schmitt/DBI/Folien_html/node42.html. It is in German. Still if your German is not too good the figures are very informative.
