Accordance apparently began in 1994 (I wasn't in Florida at the time). So, they're having their 25th. If you're a Logosian, you can participate, but only books Logos doesn't have. Else, turn in your Logos merit badge.
But then, that begs the question. Shouldn't Logos offer a 25% off, so Logosians aren't forced to go to Accordance? It's embarrassing.
And when did Logos begin? Maybe their 25th passed by and I forgot. Or maybe I should plan. 25% off the Logos library would be outstanding.
