the action or business of promoting and selling products or services, including market research and advertising.
Well, that's no help. I mean, "promoting" is right there in the definition. Pressed, I'd argue that "promoting" is about awareness, and "marketing" is about sales.
With the books coming out next year, at least at the moment the main thing I have to market is myself. To actually sell something, I more or less have to convince people I'm someone worth noting. So I've got to rely a lot on charm and personality, and being able to use those traits in a public venue with a suitable target audience.
Fortunately, I've got a venue for such a thing this weekend. I'll be at FenCon! You can check out my whole schedule right here. If you have the opportunity, come on over. I'll be on panels on geography, technobabble and series that go on too long, all topics I should be able to say clever and intelligent things about. Plus I'll be reading from Thorn of Dentonhill. Hope to see you there.
In the meantime, I've got to get down in the word mines. Always more to do down there.
