Publishers Weekly reports that internet company ReDigi, which currently sells pre-owned digital music, hopes to do the same with pre-owned ebooks. The question that arises, of course, is whether we consumers actually own the apps, music, ebooks, and other content we have paid for, and whether we can legally resell them. ReDigi is currently involved in a copyright infringement case filed by Capitol Records in the US District Court in Manhattan involving their resale of digital music and whether the first-sale doctrine applies to digital content. ReDigi claims that it is just the cyber-version of a used record store and everything it does is lawful because its technology first validates, then transfers your music to its servers without copying. If ReDigi prevails, it will "upend the way e-books and other digital products are sold, since such products would get a second life on the resale market and provide a new revenue stream for publishers and authors."
