Handy Links

The following collection of links are those that we have found useful in our own work. The Web is full of quality material, as well as a lot of material that is not quite so helpful or even accurate. Please note that these links reference sites outside our control, and we cannot be responsible for your experience at these sites or for the material there. Caveat Surfer!

Obviously, this is a dynamic collection. Please check back occasionally for new additions.
