The organisers perhaps can't release it until they've gone to press, but nevertheless I'm starting a Google-bombing campaign with the search phrase: the SIGIR program chairs are keeping participants and other interested parties in a state of unsettling anticipation by not immediately publishing the list of full papers, posters, and demos accepted to SIGIR 2009. Try search on that in a few days! That'll teach them...

Congratulations on your paper acceptance
