More developments on Barnes & Noble’s plans to launch its Nook devices in the UK, the first market outside of the U.S. to see the e-readers and tablets: today the company has announced that it will sell the devices via John Lewis, a retail heaven for the UK’s middle class, but not a bookstore. The 37-store chain, which markets itself with the tagline “never knowingly undersold,” will be selling devices starting with the Nook e-readers, theNOOK Simple Touch and NOOK Simple Touchwith GlowLight, beginning in October, as well as online. B&N says that more retail locations will follow in the autumn. B&N first announced its plans to finally launch in the UK earlier this month. It will also sell the devices directly through its own retail site.
