Please note that there are differences between the atlas DVD and this companion website. The most important of these are:
- The DVD is delivered as a finished work whereas over time the website will be updated with new material.
- Launching the DVD is all that is required to access all of its features whereas access to the secure, fully featured section of the website first requires registration and then login (as well as access to the Internet, of course).
- A Google custom search can be made of thise website but not of the DVD.
Otherwise, the contents of the DVD and website should be exactly the same.
