Amazon announced a change from a per-item fee system to subscription-based access to a library of e-books and audiobooks.

The rollout of the new system was announced Friday to some criticism and little enthusiasm since the information had already been leaked on Wednesday.

The company's new strategy to offer online reading content follows a similar transition seen in video content, from the death of the video rental stores and their per-item fee to an online subscription content library such as Netflix.

And similarly, hot items seem to be missing from the selection list, according to The New York Times.

HarperCollins, Hachette and Simon & Schuster confirmed they are not participating, but Penguin Random House and Macmillan are unconfirmed.

Additionally, similar services already exist such as Oyster Books and Scribd -- both of which are slightly cheaper, according to Huffington Post.

But Amazon has an advantage over the two because it offers more titles, according to Time. Yet it doesn't have two major names: HarperCollins and Simon & Schuster, which both the existing services provide.

One other problem found on the site is it does not direct users to the single-purchase option for the book or e-book if it doesn't exist as part of the subscription.

The Los Angeles Times did a search for Hilary Clinton's "Hard Choices," which was not found. But instead of offering links to the book on Amazon, the search turned up results for a pirate romance and a book about porn.

The subscription would cost $10 per month and is called Kindle Unlimited.

A Huffington Post article criticized the new service as a "glorified library card," since many local libraries in the country offer e-books today.

Kindle Unlimited is offered for a free 30-day trial and includes more than 600,000 titles, according to the Los Angeles Times. The service is available on Kindle and apps from iOS and Android stores.
