I know some don't approve of the free or custom ones that can be purchased from Smashwords and CreateSpace, but I'm not yet in a financial position to purchase a block myself.
Right now, I purchase the custom ISBNs both places offer, so that I'm listed as the publisher, and they're listed as the distributors.
I've run into something a little weird, and can't seem to get a real answer at Smashwords.
When I purchase a custom ISBN from CreateSpace, it appears in my Bowker(myidentifiers) account, so that I can edit the associated title's information, upload the cover and interior file.
However, when I purchase the custom ISBNs from Smashwords, the first few were listed, then disappeared from my Bowker/myidentifiers account, and none since have ever been listed in it.
My answer from Smashwords was "If CreateSpace is reselling a "My Identifiers" ISBN, then that would explain why the author has control of it at Bowker."
Bowker is the only US source for ISBNs, unless something's changed when I wasn't looking. When I applied for a publisher's account at Bowker's, I received a myidentifiers account and that is the site Bowker sends you to purchase ISBNs through.
So I don't understand why there is a 'difference', and why those I purchase from Smashwords aren't also listed in my publisher's account at Bowker/myidentifiers.
Anyone have an answer to help me understand this, please?
