Follow-up / solution / oh-duh-now-I-get-it here: http://www.laurenwayne.com/2010/04/switch-between-seller-central-and.html. Basically, ignore all of the following.
Just as a follow-up to
my last post on Search Inside This Book, I mentioned that you need a
Seller Central
account to sign up. I already had one, so I just switched my log-in email over to the one I'd given to Search Inside This Book.
Well, now I have a
caution about using an existing Seller Central account for Search Inside This Book. I'm no longer using my Seller Central account for selling anything, but when I tried to log in to it to access previous information from when I previously used that account to sell DVDs through Amazon's Marketplace, I couldn't reach the typical Seller Central page anymore, no matter how I tried.
It would only default to the Search Inside This Book page, which is a specialized author/publisher-specific interface.
Fortunately for me, this isn't disastrous, since it was a defunct seller account anyway, and I didn't badly need to get into those old files.
BUT...beware if you use your Seller Central account for serious selling that you might want to contact Amazon in advance and ask what's best. I know that having two seller accounts is actually
against Amazon rules and can lead to your being banned as a seller. But if Search Inside This Book really does make your Seller Central account inoperable as a seller account for selling on the Marketplace, then you would need a second one specifically for your publishing interests.
So, there you have it. No real advice from here, but a counsel to
seek out Amazon's take
on the situation. Maybe there's a secret link to access your Seller Central information from the publisher page, or maybe it's something they'll fix in the future.
