SO, if I say I want DRM, people cannot share my book.
But wait, if I do not choose DRM, poeple can? I mean, I use Kindle, but can someone please light me.
Or I always bought kindle books with DRM; or I don't know what it is intended to share. I mean, share, in what way?
If DRM is not applied the Kindle book file downloaded from the Kindle Store can simply be copied from that device or reader and read on any other compatible reader. With DRM applied this sort of casual copying is not possible as the book will only be readable with a device or app that can authenticate the account from which it was purchased.
The application of DRM would not affect the ability for a customer to "lend" the book to a friend, where allowed and facilitated by Amazon's systems.
When you buy a Kindle Book, You can use it on any device in your account.
You can buy 10 kindles if you like and as long as they are all registered to the amazon account under your Email address they can all read the book....
but if the book has DRM, you are limited to 5 devices
Thats 2 kindles and 2 Kindle for Pc's and 1 android device
I have about 12 Kindle devicesand sometimes I have to delete a book from 1 device before I can move it to another device.
Not really a big problem, but it does exist.
without DRM you can also copy a book from your Kindle and read it on your computer (With the Kindle for app) or load it into a friend's computer/kindle device -- that is Piracy (what I call Soft Piracy, but still Piracy.)
there are so many people out there that are desperate to be read, that Piracy is not necessarily a bad thing -- especially if you list your other books in the one pirated!
You cannot publish a free book on Amazon! 99 cents is the minimum!
Amazon has a price match policy and if you can list your book for sale somewhere else (Like SmashWords) for free, Amazon MAY match that free price!
This used to be quite common, but now Amazon has started the KDP Select program.
In the KDP Select program, you agree to be exclusive to Amazon (that means no Smashwords or Barns & Nobel etc).
For this you are automatically enroled in the Kindle Prime program where Amazon PRIME members who own Real Kindles can "Borrow" your book for free.
When this happens, you earn around $2.00 for each instance (There is a fund and the payout floats around)
Prime members may borrow 1 book per month 1 at a time (they can keep the book forever, but then they cannot borrow another untill they release it.)
with the KDP Select you can also list your book for sale to EVERYONE for free for 5 days in a calendar quarter (every 90 days) you can do this 1,2,3,4,5 days at a time. a day here two days there ... up to a total of 5 per 90 day term.
This is a convienient way of having a free book whthout having your book trapped at a zero price while you try to unravel the price match pyramid you created!
of course you are stuck with AMAZON ONLY, and they will enforce that with a vengence!
there are cases where a book is being sold by a pirate site and the Select author gets an email notice that they are in violation of the amazon terms of service!
