Your Kindle reading experience can go far beyond what's available on the Kindle store.

This technology has been around for over a decade. But now, there are many more options to send articles, documents and e-books to Kindle. These include Chrome extensions, desktop apps, and built-in support for the feature in the Kindle apps for iOS and Android.
