Maybe this belongs in Historical Research, but things can get a bit overlooked there, and I thought it deserved a wider public.
I have recently been introduced to a website called
progcovers.com
which seems an amazing resource. It has a vast collection of motor racing event programmes (car, bike and hydroplane) scanned in. Not just the covers but the pages too, some with the original owners annotated results.
It has national club level events as well as international stuff, and has uncovered a number of events my old club racer was in.
I am in awe of the time folks must have spent scanning this stuff, but we should all be grateful. I hope you find it useful.
