Found out why it was taking so long to hear about the OCLC number application--I hadn't gone through the checkout process yet! Well, this morning I checked out properly, and finally ordered my first book proof, now that I've adjusted the cover enough to fit within Createspace's weird automatic parameters. They are shrinking the cover to fit, instead of properly cutting off all the bleed space. I think it's the rainbow on the front cover messing things up.
