Bill Greenwell has launched an online research project that traces nearly a century of
New Statesman competitions. (The magazine has been publishing since 1913, and added the weekly competition in 1934, when it absorbed another journal in which the comp was a regular feature.) The site is so new that it was only up to the sixth comp last time I took a look. You'll find, among other items of interest, winning entries, judges' comments, Bill's own commentary, and glimpses of competitors who were rocking out with the Usual Suspects years before Greenwell, Ransome-Davies, et al. joined the band.

It's going to be a lot of fun watching this site develop. And we can hope that it will occupy a great deal of Bill's time and attention that he might otherwise devote to outdoing the rest of us in today's competitions.
