I have multiple titles with CreateSpace and before it changed hands, it was a very smooth process to revise exterior or interior files. Now, I have one of my titles suppressed because of copyright validation request. I've called and emailed multiple times and keep getting the runaround. A two word title promotion for the sequel is the only change made to the interior file and I get my title suppressed. This will probably be my last hurrah with CreateSpace.
Update: Since I submitted the above review, my title has been moved to Createspace Hold status (over a week now and still no change). It seems that Amazon doesn't want a title to be in circulation with another distribution outlet. Nothing prevents this if an author is using a different ISBN for another book distributor. Ingram provides hardcover and I use them for my paperback expanded distribution as well. I do have a signed agreement to exclusively distribute my audiobook titles with Amazon Audible and iTunes. But no such contract disclaimer prevents me from doing so with print titles. I have ten titles with Createspace and unbelievable the discourteous treatment I've been receiving.
