Amazon Kindle

Amazon’s Kindle Unlimited is a popular ebooks and audiobooks subscription service that gives book lovers unlimited access to a vast library of digital content. With a Kindle Unlimited membership (subscription), you can browse over 5 million ebooks, comics, magazines, and audiobooks across genres. For a flat monthly fee (currently $11.99 in the US), members can download books to any reading device and read as many as they want – Kindle e-reader, tablet, or smartphone.

Using an Amazon Kindle e-reader or the Kindle app turns any modern device into an ebook reading device. Kindle Unlimited lets you instantly borrow and download eligible books – simply find a Kindle Unlimited title in the Kindle Store and tap Read for Free to add it to your library. Once borrowed, books download directly to your Kindle or Kindle app, and you can read them offline anytime. Your membership lets you borrow up to 20 Kindle Unlimited books (or audiobooks) at once.

What’s Included with Kindle Unlimited:

Kindle Unlimited’s library includes a diverse range of titles and formats. Amazon says members have access to more than 5 million digital books, audiobooks, magazines, comics and graphic novels, spanning genres like mystery, romance, sci-fi, fantasy, memoir, and more. Key content types are:
