As explained in this article from the Consumerist magazine, it's completely ethical to download the eBook versions of books you already own, but it's illegal in the US.
Here's where it gets sticky. You own the US version of the Harry Potter series, and you download a torrent of the Harry Potter series so you can enjoy the same media on your iPad. The torrent comes with the UK version, Harry Potter and the Philosopher's Stone instead of the US version, Harry Potter and the Sorcerer's Stone. Or how about 2nd editions of biographies?
If you buy the print copy of a book and you want to read it as an e-book, the only legal and ethical way is to scan it yourself.
Ethically, you should only download the exact e-book version of the copy you own.
Yes, but how do you verify that before you download? Most sources for pirate e-books don't have ISBN numbers listed.
So, from my point of view, it would be nice to this to be legal![]()
This. Like I said before it doesn't make sense that it's illegal.
Ethics may get you a hung jury. Laws will put you in the defendants seat. Digital media should be treated just like print/"real" media. And it is treated that way from a legal perspective.
If you have a paper back book and now you want a hard back, you walk into Barnes and Noble and buy the hardback version. If the situation was reversed and you owned the digital copy, and then decide later you want a paper back, then you got to the store and buy a paper back copy. You don't just walk into the store put the book in you coat and say, "well I already own the digital copy, so it's ok." Right now, downloading pirated media is illegal. If you want to change the law, write your congressman or run for congress yourself.
Disclaimer: I fully condone downloading copies of media you already have. However I know that doing so is illegal.
