Every eBook is released under a licence. Even if there is no licence specifically identified then it is covered under the general copyright law. If you purchased the book and it was not released under a licence that permits redistribution then you should assume that giving away copies to friends is forbidden.
Generally you can find the licence that ...
Drm-Free doesn't necessarily mean copyright-free. If the book is licensed as such that it is available freely to anyone, then you are allowed to make copies. If there is some license or terms of usage attached to the book that suggests it is not free to distribute, then you are not allowed to make copies and give it away.
The one I use is Luzme It queries several stores including Kobo, Amazon, B&N and in several countries.
It then for each book shows the price that it last saw for each source and country.
It is searchable by book name and author and series, although the series data is not complete as it comes from the stores.
You can set up a wishlist of books and ...
There was a study1 done by Laurina Zhang about the effects of DRM on music sales. In her conclusion1 she states:
My analysis in this paper, based on a large representative sample of
albums from all four major record companies, sheds light on this
question. I find that the removal of DRM increases digital sales by
While this does not directly ...
Calibre is a downloadable (free, donations accepted) application that will allow you to search over multiple stores, for content. Using the get books function, to provide information like comparative pricing between retailers and DRM status of the work at different retailers.
As the author of 5 tech books (all available in ebook format and published by O'Reilly Media), I can tell you that the O'Reilly party line is essentially that "DRM logic is flawed". We're in a transition period right now and you have to have "faith in the base logic market" and take into account how "DRM interferes with the user experience".
My personal ...
According to Wikipedia, there are four main ebook DRM schemes in common use today, one each from Amazon, Adobe, Apple, and the Marlin Trust Management Organization (MTMO).
Amazon's DRM is an adaption of the original Mobipocket encryption, and is applied to Amazon's Mobipocket, KF8 and Topaz format ebooks.
Adobe's Adept DRM is applied to ePubs and PDFs, and ...
Yes there are. The one I remember is Inkmesh.
You can filter by price, type (ebook, magazine, audiobook, etc.) device and language. Its database has large gaps though.
This site does not provide DRM status.
Ebooks are protected by the Digital Milenium Copyright Act (DMCA), so you are only legally able to do what the DRM allows. Most of it depends upon the company who sells the ebook, and the publisher.
If you are allowed to sign on to multiple readers with the same account.
As long as the terms of whoever the account is with allow you to share accounts.
The premise in your question's title does not seem to be accurate. E.g. Amazon's terms and conditions state that you don't own the ebook, you buy the right to view it on your Kindle.
All content included in or made available through any Amazon Service, such as text, graphics, logos, button icons, images, audio clips, digital downloads, and data ...
Adding some rationale to the existing answers:
A common reason an author/publisher would not want you copying even a free ebook is that even "free" sales boost the book's number and visibility. An ebook the author gives away freely to 1,000 readers is better for him than giving it to 1 person who then emails it to 1,000 friends.
If the book is still ...
Well, according to this blog, it says Bill C-11 (Copyright Modernization Act, which amends the existing provisions of the Copyright Act) has made it illegal to break DRM in Canada.
An excerpt from the actual Bill C-11 (Section 1f):
Bill C-11 prohibits the circumvention of any access control installed
on a work, performer’s performance fixed in a sound ...
Some DRM schemas are severely restricted to the devices and software they run on. For example, MS Reader's .lit files DRM were toed to MS Reader software that ONLY ran on Windows.
So if you are forced to go without a Windows based PC device (e.g. use Linux and Android for your desktop/mobile; and have no money or other reasons not to own ...
I don't know if there are studies into soft DRM, but there are studies
on difference in behaviour between people that are anonymous and people that are not. The non-anonymous generally being more "honest".
Removing soft DRM would rely on the non-anonymous person to do so, before handing the ebook on to someone else. Not doing so would have her/him run the ...
the only case in which you may legally copy an ebook and pass to a friend of yours is when (a) there is a "copyright" (in a broad sense of the term), and (b) the copyright says you may freely distribute the ebook (because it is in the public domain, or is published under a Creative Commons license). If there is no copyright at all, you should suppose that ...
If you are only selling through your own web store, I suggest looking into 'social DRM' - that is, adding information to each individually sold ebook that identifies the purchaser. There are some providers who will add encoded info invisibly throughout the book.
But personally I'd recommend a pretty 'ex Libris' page after the title page giving name of the ...
According to the Kobo website:
When do I need to use Adobe Digital Editions?
If you use any of Kobo's free reading apps or a Kobo eReader, you may
never need to use Digital Editions at all. Kobo's reading apps and
eReader can automatically download most books from the Kobo Store, and
update your library with them.
The exceptions are when:
If you look at the bottom of the page you linked:
As you can see, this book is listed as "Senza DRM" (DRM-Free on the English language site).
You'll also see books with Adobe DRM such as "Mitologia classica"
Per your comments I have read on EditionGuard that offers an extension for WordPress sites. There is a fee associated with content but my understanding is you upload your content to them, you can sell through your CMS and they will send a DRM ePub. I have not tested this yet, but I had planned to in the future when I had time. Also, note this is for only ....
The easiest thing to add DRM to your e-books is to publish via a publisher who will add the DRM for you.
The DRM enforcement schemes normally rely on a set of keys being available in the consumer device, in order to decode the encoded data. The number of such keys is limited and they (or their private counterparts, depending on the scheme) are therefore ...
Some of the more enlightened publishers, including O'Reilly and Pragmatic Programmers, publish their technical books without DRM and in the major formats including PDF, .mobi (for Kindles) and EPUB. I expect other publishers will do likewise. Others watermark their books e.g. where the footer might say 'for Julian Harty' where the books are not DRM'd either....
This question is a little subjective (is it better) and broad (there are many different DRM formats).
With that being said, in my personal experience, I prefer DRM-free ebooks. They work better in various readers that support the given document format. I don't always like to use my Sony Reader for books that I purchase (usually epubs). For programming ...
As stated in Consumerist, as far as Amazon goes (the rules are usually similar [not identical] for B&N):
You can download a book an unlimited number of times.
In most cases, you can download the book to 6 devices. If you need to download it to more devices than that, you can request that Amazon
release additional licenses for the book. ...
For me, Soft DRM is a viable option that helps the book provider to identify who they provided the book for/to. I'm not aware of any formal analysis, or reports, of how Soft DRM fares in terms of things like unauthorized copying. I've found 'soft copies' of books online that were watermarked for someone else so unauthorized copies/distribution exists. ...
Create a watermark pdf which contains the footer using imagemagick:
convert -background none -geometry +0+0 -fill \#000000 -pointsize 12 label:"From the library of..." -set label '' -page A4 watermark.pdf
It creates a simple pdf ( size: A4 ) with the text From the library of... at the bottom left corner. You might change the font, the position of the text, ...
The most effective way to manage your Nook books on your Kindle (without removing the DRM) is to obtain the Nook for Android app and sideload it on to the Kindle (you'll need a Fire or later model to do this).
If you don't have another Android device handy, you will need to find a means to download the Nook APK file to your computer.
You may want to try using the Calibre Ebook Manager with the deDRM plugin to get the ebook files, sans-DRM, and then move them onto the Kindle. It works, but it won't sync them or automatically move newly purchased books; each book must be done individually.
The Digital Reader has some helpful tutorials on how to do this:
To strip DRM from Kindle ebooks
Go to the original statement. This includes
Tom Doherty Associates, publishers of Tor and Forge, is pleased to announce that all of their ebooks are now available DRM-free from Amazon, B&N, Apple, Kobo, Google, and most other major ebook retailers.
The new DRM-free editions are available from the same retailers that have sold Tor e-books in ...
