KDP is poorly ran and though it may seem at first to be a good option I strongly advice you seek another service. I am a published author with several titles to my name - including a couple of self-published works. The only troubles I have ever had is with KDP who for whatever reason is blocking the republication of my book - though they sold the first edition - arguing that I cannot use a pen name (though many do) and that my "new" title to much resembled my previous book already published (which is of course the first edition). After several days and a dozen emails it is clear there is no getting through to these people and no way to contact someone in person. I have pointed out that its a second edition of a book no longer in print that they previously sold so of course the new edition is "similar"??? They even sent me a link of my own book as proof as to why they could not allow another similar book to be printed and when I point out that its the same book and I am the same author they simply ignore that point and just repeat the exact same nonsensical position. So instead I went back to Ingram with this title and got it up and running in no time - and surprise its available for sale on Amazon - KDP your a joke - and your customer service is horrible.
