Bestselling authors and writers are up in arms against international retailer Amazon in its contract dispute with publisher Hachette Book Group.

Amazon in return meanwhile, published a note to the public, explaining its side of the battle with Hachette involving e-book pricing.

A group of bestselling authors,  will take out a full page advertorial in New York Times Sunday Edition expressing their opinion on the ongoing dispute.

"As writers- most of us not published by Hachette-we feel strongly that no bookseller should block the sale of books or otherwise prevent or discourage customers from ordering or receiving the books they want, " the authors was quoted as saying in the letter.

Business Standard further quoted the letter as saying that the authors is calling on Amazon, " to resolve its dispute with Hachette without further hurting authors and without blocking or otherwise delaying the sales of books to its customers."

Guardian reported, that several famous authors such as Stephen King, Donna Tartt and Paul Aster signed the ad.

Amazon, for its part asked readers to support its fight against Hachette, in its note published in ReadersUnited.com web site the company stated,  "We will never give up our fight for reasonable e-book prices. We know making books more affordable is good for book culture. We'd like your help. Please email Hachette and copy us."

Amazon has disputed that the e-book price range of $14.99 to $19.99 is "unjustifiably high," when compared to physical copies, e-books cost less to produce.

Under the new contract term proposal, Amazon is asking Hachette to lower its e-book prices to at least $9.99 and a 30 percent cut from sales.

Authors meanwhile, branded Amazon's move against Hachette as "thuggish behavior." Amazon has reportedly blocked pre-order on Hachette books, took away discounts and delayed shipments.

The e-book industry is a multi-billion venture and based on the Global e-book revenue from 2009 to 2016 by Statista.com, earnings are growing and that in 2010, e-book revenue in North America totaled to $1.2 billion in U.S. dollars.
