The Eastern Museum of Motor Racing located on Route 15 a few miles South of Williams Grove Speedway has an extensive research library. In it has many of the weekly trade papers on micro-film and has National Speed Sport News from 1934 on on micro-film. Also the Chris Economaki collection is also housed there. the web site is
www.emmr.org and you can find out more info there. You can easily speed 6 hours in there and still want more, I know I have many times done that. It is $20 per year to join and that is well worth it. Lynn Paxton and his group go out of their way to make this one of the best in the country. free admission, they just ask for a donation. Excellent gift shop by the way!
