All information about current and future NPL conventions is on the Convention web site:
Old FAQ for Conventions.
The NPL has been holding conventions since 1883. The 2008 convention was the 169th. Willz, the League Historian, has compiled a complete list of all conventions and the editors in place at each convention.
Pictures and convention reports from previous conventions will be published as they are obtained. Some pictures are available to Members Only.
Mini-conventions are held on an ad hoc basis around the country. Click below for some photographs, reports, and miscellanea concerning various recent regional gatherings.
Greetings! At 12:00 noon EST, Monday September 4th 2006, I'll be posting a 12-puzzle 'ganza online at http://www.markhalpin.com/laborintensive.html. The timing might give you a clue to the theme. There's a (modest) prize for the first person to solve everything. Hope many of you play!
