Amazon has done it again, and as usual, the winners are readers.

This morning the company launched Kindle Unlimited, which after a very nice 30-day free trial will allow readers unlimited reading or listening from among over 639,000 Kindle Books and over 2,000 Audible.com audiobooks. The service will cost $9.99 a month after the free trial, and one easy way to understand what’s being offered is that it’s like “Netflix for ebooks.”

While we expect the catalog of books, author and publishers participating in Kindle Unlimited to blow past the million-title mark this year and continue to expand, the selection even at launch is pretty dazzling. This morning we selected seven titles to include in our daily BookGorilla email alert, just to give our readers a taste of the kind of top-tier, A-list bestsellers that are available absolutely FREE during the free trial:

• The Hunger Games By Suzanne Collins
• Capital in the Twenty-First Century By Thomas Piketty
• War Brides By Helen Bryan
• Flash Boys: A Wall Street Revolt By Michael Lewis
• That Summer Night (Callaways #6) By Barbara Freethy
• Everything Is Illuminated: A Novel By Jonathan Safran Foer
• The Best Medicine (A Bell Harbor Novel) By Tracy Brogan

Winners and Losers

We’ll be watching closely to see what new titles become available, but based on what we see already it seems likely that Kindle Unlimited will be as big a disruptive force for “business as usual” in the publishing world as the Kindle itself has been. We will no doubt continue to see misguided analyses claiming that Amazon will be competing with this, that and the other existing service, but any such “competition” will likely be akin to the centuries-old competition between the hammer and the nail: usually, one doesn’t even get to hear the nail say “ouch.” Nobody is in a position to compete with Amazon on this terrain.

Amazon seems committed to a pretty generous royalty structure for enrolled titles, which we think will ultimately amount to about $2 a copy for authors who participate in its KDP Select program. Given recent negotiations — and the Hachette stalemate — between Amazon and some large publishers, we wouldn’t hazard a guess as to what share those publishers and their associated authors might receive, but publishers who stay on the sidelines may find themselves in an untenable position — both with their authors and with their own corporate bean-counters — as the Kindle Unlimited catalog grows.

For people who read a lot, Kindle Unlimited is going to be awesome. We won’t talk ourselves blue in the face trying to persuade you beyond noting that the seven very popular titles listed above would currently cost you $66.15 in the Kindle Store without Kindle Unlimited. After all, we think all of us will make better use of our time looking for great books to download FREE.

It’s probably silly of us to take any pleasure in having predicted this program almost exactly six years ago on pages 90-91 of the paperback edition of The Complete User’s Guide to the Amazing Amazon Kindle, and we didn’t get it exactly right, anyway. We called it Kindle Buffet, said it would be a Kindle reading subscription plan “on steroids,” and we were way off on how such an offering would be priced: we said it could cost as much as $50 a month. My, how things have changed!
