As someone who self-publishes (five times), I am still a little confused as to the best sequence to buy an ISBN and on which platform to publish. After buying an ISBN for may latest book from you, I went to B&N first, since it tells me the minimum price that I can charge for the book. Then I had to go back and figure out how to change the price on your site, at which time I learned that I could just got to B&N first and skip your site, because B&N references Bowker. All of this would have been good to know before I started.

This was easy, clear and the service generated our ISBN numbers and scan on-the-spot, and collected the information needed to register the book(s) in a national registry. It was a smooth and quite painless process.

As a first time book, author and publisher, this was a seamless process and by having the things that was required to complete the process on the website, made it very easy and efficient and effective to complete

Hi Pam! Guy from ISBNdirect here 👋🏻 Thank you for your review. You can download the barcode for your ISBN on the ISBNs page in your account. Just click the barcode icon on the far right of your ISBN's row and save the file to place on your back cover. If you're publishing a paperback on Amazon KDP, you don't need to add it yourself. KDP places the barcode on your cover automatically once you enter the ISBN. If you meant something else, send us a message through the help widget in your account and we'll help you out.
