It's an event organized by the Bukowski-Society
, usually around Buks birthday in his town of birth, Andernach (Germany).
There are addresses by Bukowski-experts or other people, who have something to say on the subject.
This year's program is still in the making, but there will be an address by David Calonne and one by a dermatologist about Buks skin-deseases. Also an address by a girl, who's working on her PhD about Bukowski at the moment - known here as 'Dora'. Other addresses and the usual Saturday-evening-event are not sure yet.
You can see a couple of pics from last year's symposium here:
