+Digital Rights Management (DRM)
+===============================================
+
+Digital rights management (DRM) is a generic term for access control
+technologies that can be used by hardware manufacturers, publishers, copyright
+holders and individuals to try to impose limitations on the usage of digital
+content and devices. It is also, sometimes, disparagingly described as Digital
+Restrictions Management. The term is used to describe any technology which
+inhibits uses (legitimate or otherwise) of digital content that were not
+desired or foreseen by the content provider. The term generally doesn't refer
+to other forms of copy protection which can be circumvented without modifying
+the file or device, such as serial numbers or key-files. It can also refer to
+restrictions associated with specific instances of digital works or devices.
+DRM technologies attempt to control use of digital media by preventing access,
+copying or conversion to other formats by end users. See `wikipedia
+<http://en.wikipedia.org/wiki/Digital_rights_management>`_.
+
+
+What does DRM imply for me personally?
+------------------------------------------
+
+When you buy an e-book with DRM you don't really own it but have purchased the
+permission to use it in a manner dictated to you by the seller. DRM limits what
+you can do with e-books you have "bought". Often people who buy books with DRM
+are unaware of the extent of these restrictions. These restrictions prevent you
+from reformatting the e-book to your liking, including making stylistic changes
+like adjusting the font sizes, although there is software that empowers you to
+do such things for non DRM books. People are often surprised that an e-book
+they have bought in a particular format cannot be converted to another format
+if the e-book has DRM. So if you have an Amazon Kindle and buy a book sold by
+Barnes and Nobles, you should know that if that e-book has DRM you will not be
+able to read it on your Kindle. Notice that I am talking about a book you buy,
+not steal or pirate but BUY.
+
+
+What does DRM do for authors?
+----------------------------------
+
+Publishers of DRMed e-books argue that the DRM is all for the sake of authors
+and to protect their artistic integrity and prevent piracy. But DRM does NOT
+prevent piracy. People who want to pirate content or use pirated content still
+do it and succeed. The three major DRM schemes for e-books today are run by
+Amazon, Adobe and Barnes and Noble and all three DRM schemes have been cracked.
+All DRM does is inconvenience legitimate users. It can be argued that it
+actually harms authors as people who would have bought the book choose to find
+a pirated version as they are not willing to put up with DRM. Those that would
+pirate in the absence of DRM do so in its presence as well. To reiterate, the
+key point is that DRM *does not prevent piracy*. So DRM is not only pointless
+and harmful to buyers of e-books but also a waste of money.
+
+
+DRM and freedom
+-------------------
+
+Although digital content can be used to make information as well as creative
+works easily available to everyone and empower humanity, this is not in the
+interests of some publishers who want to steer people away from this
+possibility of freedom simply to maintain their relevance in world developing
+so fast that they cant keep up.
+
+
+Why does calibre not support DRM?
+-------------------------------------
+
+calibre is open source software while DRM by its very nature is closed. If
+calibre were to support opening or viewing DRM files it could be trivially
+modified to be used as a tool for DRM removal which is illegal under today's
+laws. Open source software and DRM are a clash of principles. While DRM is all
+about controlling the user open source software is about empowering the user.
+The two simply can not coexist.
+
+
+What is calibre's view on content providers?
+------------------------------------------------
+
+We firmly believe that authors and other content providers should be
+compensated for their efforts, but DRM is not the way to go about it. We are
+developing this database of DRM-free e-books from various sources to help you
+find DRM-free alternatives and to help independent authors and publishers of
+DRM-free e-books publicize their content. We hope you will find this useful and
+we request that you do not pirate the content made available to you here.
+
+
+How can I help fight DRM?
+-----------------------------
+
+As somebody who reads and buys e-books you can help fight DRM. Do not buy
+e-books with DRM. There are some publishers who publish DRM-free e-books. Make
+an effort to see if they carry the e-book you are looking for. If you like
+books by certain independent authors that sell DRM-free e-books and you can
+afford it make donations to them. This is money well spent as their e-books
+tend to be cheaper (there may be exceptions) than the ones you would buy from
+publishers of DRMed books and would probably work on all devices you own in the
+future saving you the cost of buying the e-book again. Do not discourage
+publishers and authors of DRM-free e-books by pirating their content. Content
+providers deserve compensation for their efforts. Do not punish them for trying
+to make your reading experience better by making available DRM-free e-books. In
+the long run this is detrimental to you.  If you have bought books from sellers
+that carry both DRMed as well as DRM-free books, not knowing if they carry DRM
+or not make it a point to leave a comment or review on the website informing
+future buyers of its DRM status. Many sellers do not think it important to
+clearly indicate to their buyers if an e-book carries DRM or not.  `Here
+<https://www.defectivebydesign.org/guide/ebooks>` you will find a Guide to
+DRM-free living.

 How do I use purchased EPUB books with calibre (or what do I do with .acsm files)?
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Most purchased EPUB books have `DRM <https://drmfree.calibre-ebook.com/about#drm>`_. This prevents calibre from opening them. You can still use calibre to store and transfer them to your e-book reader. First, you must authorize your reader on a windows machine with Adobe Digital Editions. Once this is done, EPUB books transferred with calibre will work fine on your reader. When you purchase an epub book from a website, you will get an ".acsm" file. This file should be opened with Adobe Digital Editions, which will then download the actual ".epub" e-book. The e-book file will be stored in the folder "My Digital Editions", from where you can add it to calibre.
