If you buy a book at the book shop, you own it, and are free to do exactly as you wish with it. You might be surprised to hear that the same is not true of ebooks and other downloaded media. In fact, as Aaron Personowski and Jason Schultz discuss, the digital world is an incredibly complicated place when it comes to ownership.

Chances are if you own an iPod, Kindle or even a desktop or laptop you are no stranger to the world of the digital download. It is becoming more and more common to simply pay for a digital copy of a song, book or film, rather than worrying about cumbersome physical objects. Who even has time to wait for an Amazon delivery these days, anyway? The digital download has done wonders for the instant gratification of consumers, but at what cost? Like it or not, each time you click ‘pay now’ on a digital purchase, you are entering a new and confusing world, rife with rules, regimes and regulations that restrict how you interact with your downloads.

Authors Aaron Perzanowski and Jason Schultz use their book to delve into the complex, jargon-ridden world of the rights of digital consumers, to uncover the mystery of whether we can really be considered ‘owners’ of our digitalia. As the owner of a physical object you enjoy certain freedoms; if you have a collection of print books, you are free to annotate them, modify them, or even destroy them if you want to. The same however, cannot be said to the ‘owners’ of downloaded goods.

Every time you buy an ebook from Amazon or a song from iTunes you sign an end-user licence agreement (EULA) – let’s be honest, you have probably never read it – the contents of which are far removed from the freedom we enjoy with physical ownership. Consumers do not actually own digital purchases, they license them and have the permission to read, listen to, play, or watch them. Slightly more worrying is the fact that the company providing the software used to access these files effectively has control over a user’s digital library.

Here’s an interesting case. In July 2009 Amazon remotely, and without warning, wiped (irony of ironies) George Orwell’s ‘Nineteen Eighty-Four’ and ‘Animal Farm’ from all Kindle ereaders, following a dispute with the publishers.

Small fry, perhaps? Permissible collateral damage? Well, what happens when devices, or corporations, become obsolete? That’s what happened to HDGIANTS Inc, a former distributor of high-quality audio and video files. When it went bankrupt, its servers were switched off, and with that, portions of the digital libraries of thousands of paying customers evaporated.

So how content should consumers be with their content? A bookshop cannot, as Schultz and Perzanowski point out, creep into your house in the middle of the night and reclaim the contents of your physical shelves – so why can digital providers? Is it fair that book lovers and audiophiles are charged prices akin to a physical copy for a digital download that is completely at the mercy of publishers and licensers? What is the benefit to the consumer of opting for digital files? Are the benefits of reducing waste and getting instant gratification really worth it?

‘The End of Ownership’ presents the confusing world of the digital consumer in wonderfully accessible prose, replacing hideous jargon with the simplest of analogies, from thieving bookshops to the goblins from Harry Potter. It will answer the questions you have regarding digital ownership, and it’s inevitable that more than a few of them have never even crossed your mind.

In an increasingly complex world, plagued by unreadable (certainly unread) terms and conditions, it is more than a little refreshing to have something explained in good, plain English.
