Book Burro - Seattle Public Library + Firefox 1.0 Fix
Thanks to Carrick Mundell, adding Seattle Public Library to Book Burro was a synch.

I ran into a weird issue with the new configuration code - Firefox 1.0 doesn't seem to like:
myCheckBox.addEventListener("command", function() { foo(this); }, false);
While both FF1.5 and FF1.0 work with:
myCheckBox.setAttribute('oncommand', 'foo(this)');
So if you haven't upgraded to Firefox 1.5, you need to upgrade to Book Burro 0.22.
