That all could change if a new ruling by the Court gains traction, according to GoodEReader, an e-reading blog. Yesterday, July 5, 2012, the Court of Justice of the European Union ruled that "original buyers of a digital product license can resell that license to a third party, providing they no longer use the digital product themselves. This could have ramifications for e-books, which, like software, are licensed digital files." Let's hope this one makes it over the pond.
TOLD you it was a good idea. See this article, "Used ebooks coming to a thrift store near you?"
