Harry's full name

[Snark Knight]

Starborn is the key, I think.  Since Harry is starborn and has power over Outsiders and Outsiders have no power over him, Harry can say his name, or in this case use his name without harm or fear of attack from using it.

Furthermore, there was a WOJ that, basically, Harry is a somewhat unique case where others trying to use his name against him would instead be making themselves vulnerable rather than getting power over him.  That was in reference to Harry as narrator ending SF with his name and "conjure by it at your own risk".

That might be another aspect of being starborn besides just immunity to and influence over outsiders that hasn't been explored yet.

That's very interesting... do you have a cite, where we can see the whole WoJ in context?

(also, d'you know if this is another facet of the Starborn thing, or is it something else?)

I think he doesn't have the power to "summon" them.
The thing he calls a "summoning" is more like a highly-interesting lure.

  Harry does have the power to "summon," and he did summon Mother Winter in Cold Days.. Declarative statement from Mother Winter," page 320

More teeth showed. "He summoned me, the precious thing."

There is more on the page as to why Mother Winter after she was summoned proceeded to drag Harry back to her cottage. She explained to Mother Summer that Harry had used "certain names," thus was able to summon her and that he knows who the adversary was.. All of this leads up to the decision for Mother Summer to take Harry and show him the Gates so he will fully understand what is at stake..

Hmmm.
Excellent find, TYVM!

Yes, I believe there was a Q&A session on YouTube where Jim said this.  I think it was posted on YouTube.  That was many years ago, probably within a year of when Cold Days came out, because someone asked Jim about the way Harry used his name like it was a weapon he could use to force the HWWBf to answer him. 

Let's see, Cold Days was released November 27, 2012.  So, to find that exact video, you would probably have to go through every video Jim did in 2013 or at the very end of 2012, that is still posted online.

A transcript might also by posted in the WoJ section, under Frequently Asked Questions, though there is an awful lot stuff to go through there.

OK, I looked at the WoJ section and found this.  It wasn't as hard to find as I feared it would be.  It came from a Q&A Jim did at a book signing in 2013 in Kansas City.

Q - "When Harry is battling Sharkface in the end, is that all in his head, or did everybody there hear?
A - And the answer to that is yes. It’s all going on in his head, and everybody there heard. Which, if you’ll remember the closing to book 1, because book 1 was written from the perspective of a guy who has already finished his story, um, all the books are really, they're him looking back, you get to the end book 1, and Harry says “My name is Harry Blackstone Copperfield Dresden, but conjure by it at your own risk” which, you know, there’s a reason for that. Figured I’d just throw that in there. Really, Harry’s one of those guys whose name is more dangerous to other people than it is to him, in a lot of ways, a lot of people would be vulnerable by doing that, he’s not. We’ll get to see that in the future."

I don't think we haven't seen Harry use his name like that since then.  Makes me wonder when it will happen again.
