Over at his Amazon blog, Nat Gertler (organizer of the annual 24 Hour Comics events and author of Complete Idiot's Guide to Creating a Graphic Novel) gives some tips on planning a book signing event, "because there is more to doing this than just showing up."
He also gives this advice:
signings don't always work. Even when you do everything right, even if the retailer does his part in publicizing the event (but especially if he doesn't), it's quite possible that no one will show up. Don't panic, and don't assume that this is a sign of your failure. I've seen mighty popular folks not get the crowd. But here's the thing to remember - if no one shows up, no one sees how badly it went!By the way, 24 Hour Comics 2006 is coming up October 7.
