Kindle direct publishing by Amazon

That's not a problem for me. A writer must be original, nobody wants to be copied by another one, as writing a book is not easy and takes its time.

@Meramar I know, but you can write phrases that have been written in the past and you do not even know. Better to have a very good duplicate checker, because Amazon is really strict.

@kepweng No I am not, one of my friend wrote some Kindle books and she told me how careful you must be before submitting to Amazon.

Until now, I published only one paper book three years ago. But I want to publish the same one and a second one I wrote as an ebook. Besides, I am working on my third one. Do you have positiv experiences with Lulu?

@Meramar Yes. They are free to publish with if you do everything yourself. And your book gets a free ISBN but it is Lulu-owned and can only be used there and for the book you get it for. And you can distribute your books to online retailers like Amazon, B&N, etc. and it's free. The only thing you pay for is the proof copy of the book that you have to buy before you approve it for distribution. But you pay a discounted author price for it, not the price you set the book at, so you spend less. And on lulu itself you can discount your book, plus they offer discounts themselves. Maybe that can increase sales. Books are also POD by the way.

@lovebuglena That sounds interesting! Thank's for sharing the information.

Thank you!

Same happens to me. I will see how it works.
