N2NC and team have now extended the CQ WW online database back to 1953. Hard to believe there were only 167 phone entries and 187 CW entries back then.
CQ WW Online Database 1953-2013
Total Phone entries 168,423
Total CW entries 166,369
One cool thing to do is to see the winning score every year for any combination of country/category.
