Amazon has announced the opening up of its Kindle Digital Text Platform outside of North America. The service, which allows authors to self-publish, was previously only available in the United States.

Now, authors writing in English, German or French can upload and sell their books through the Kindle Store across the world. That can then be downloaded to Kindle devices, though it can't yet be accessed by regular PCs. Authors receive a 35% royalty on the list price.

This announcement serves as a reminder that Amazon isn't just considering the Kindle as a device, but as a tight ecosystem akin to iPod & iTunes. Of course, there's no guarantee yet that it'll be as successful as Apple's efforts - consumers have so far remained lukewarm on eBook Readers.
