When I started posting "The Eagle and the Dragon" for publication via Createspace, I elected to purchase a Gowker ISBN @ $100. I chose not to launch with extended distribution, as I wanted to keep the price down. Last week, with Kindle selling well, I decided to elect extended distribution, to get it into B&N and Ingram. The three choices for extended distro are Bookstores, createspace direct, and libraries and instiutions. The first two were selectable, the thrid greyed out as inelgible due to non-CS ISBN. No matter, I went ahead and also raised the price accordingly. After a few days, only my short story "Come, Follow Me" showed up on B&N. A call to CS told me that the CS ISBN is required for all three, just not the last one that was rejected. My option are to give up B&N, Ingram and the route to Nook and overdrive, or to republish under a CS ISBN. I am holding off on making the change, and backing the price back down. I would like to get recommendations on this: in particular, if I retire the current paid-for ISBN, can I retain it for future use. It is, I understand, now permanently linked to my name and title. Comments please! CS does not make this clear at ISBN selection, or I don't recall they did. Everyone should be aware of this before purchasing an ISBN for CS publications.
