Great for Indianapolis Motor Speedway history buffs

While surfing, recently, I came across a wonderful website called The First Superspeedway.
Here is an excerpt from the site's overview:

Auto racing historians and journalists will find this Web site a gold mine. This is the best collection of pre-World War I American oval track auto racing research in the world. This site is chock full of volumes of material about the earliest oval horse track races, and, of course, the seminal races at the Indianapolis Motor Speedway. As a bonus, there's some great road racing content as well, such as original articles about the brutally hot first French Grand Prix in 1906. Here's a quick overview of what you'll find:

Hundreds of 90 to 100+ year-old first-hand account articles.
Entire books written by people from the era scanned in PDF format.
Compelling scanned images lifted from the articles – some examples are on this page.
Pen and ink artwork you can use as free clip art
Original articles by me, Mark Dill

The site is, indeed, a treasure for racing history buffs, and the old photographs are fantastic. The books and articles are linked to pdf format, so it is necessary to have Adobe Reader downloaded to your computer, but the time it takes to download is well worth it for this site alone.
