Took a look at their holdings and they have some real intersting films and videos. Looks like a lot of scoring and timing journals as well, plus journals, notebooks, diaries and a plethora of other written documents.
Would be worth a drive up to spend a few days digging through a lot of stuff.
Would love to see a sampling of the type of materials they intend to make available online. Hopefully some in depth stuff. NASCAR stats and such online are decent from about the mid 80's to present, but relatively superficial before then. For example I can point you to a place that will tell you won just about any race of any year. But if ya want to know who finished 10th, that requires some serious digging. And qualifying results for say 1969, forget it.
