If you are an eBook fan, I guess you must know the fact that not all the eBooks downloaded online are DRM free. Especially books from the main eBook stores on the market, such as Amazon, Kobo, Google Play and Nook. Even though we download some free eBooks, they are also protected with DRM. For DRMed books, we are not allowed to copy, print, share with friends and family or read them on the devices we like. It’s really annoying, right? In order to avoid purchasing DRM protected eBooks, can we tell if an eBook has DRM before we buy it? Or can we check whether the purchased eBooks are DRMed? How to? Don’t worry. In this article, I will teach you how to for details? For purchasing DRM free eBooks, you can click here to learn about some online eBook shops that provide us eBooks without DRM.

What does DRM protected mean

To begin with, let’s learn something about DRM protected eBooks. Currently most eBooks typically use DRM technology to limit copying, sharing or printing of eBooks. DRM protected books are always limited to be used on limited number of reading devices. Some publishers even prevent any copying or printing. For some users, you may be still confused about it, but I guess you will know it after reading following examples.

--You bought a Kindle book and transfer it to Nook eReader or iBooks, but they told you it cannot be opened at all.

--You found an interesting Kindle, Kobo or Nook book and want to share it with your best friends or family, but when you transfer or copy it to him, he cannot open it because of copyright protection.

--You purchase a guide book, such as a cook book or text book and need to print some useful pages out for convenient use, but when you tried to print, they told you “this book is not allowed to be printed”.

--You only have a Kindle device, but the book you like is only in EPUB formats, you tried to convert EPUB to Kindle format, the eBook converter told you “This book is DRMed, we cannot convert it”.

--If you don’t like the cover of your downloaded eBooks, owing to DRM, you cannot change its cover to a more beautiful picture either.

How to tell if a Kindle book has DRM? Usually we can check a Kindle eBook has DRM or not via its product details. As the image below shows, we can tell if a book has DRM protection in 3 cases.

1. If it says “Simultaneous Device Usage: Unlimited”, obviously, the book is DRM free.

2. If it says nothing, it indicates the book is DRM protected.

3. If it has a “Simultaneous Device Usage”, but it gives a number of licenses, such as “Up to 5 simultaneous devices”, then it will have DRM.

Simply click on the cover of eBook you like, then you will come to the eBook details page. From the bottom of this page, just as the image shows, according to the “Download options” item, we can clearly know the book is DRM protected or DRM free.
