SEATTLE — Amazon.com has taught readers that they do not need bookstores. Now it is encouraging writers to cast aside their publishers.  Laurel Savilleâs memoir about her mother was self-published at first. It is scheduled to be published by Amazon next month.  Amazon will publish 122 books this fall in an array of genres, in both physical and e-book form. It is a striking acceleration of the retailer’s fledging publishing program that will place Amazon squarely in competition with the New York houses that are also its most prominent suppliers.  It has set up a flagship line run by a publishing veteran, Laurence Kirshbaum, to bring out brand-name fiction and nonfiction. It signed its first deal with the self-help author Tim Ferriss. Last week it announced a memoir by the actress and director Penny Marshall, for which it paid $800,000, a person with direct knowledge of the deal said.  Publishers say Amazon is aggressively wooing some of their top authors. And the company is gnawing away at the services that publishers, critics and agents used to provide.  Several large publishers declined to speak on the record about Amazon’s efforts. “Publishers are terrified and don’t know what to do,” said Dennis Loy Johnson of Melville House, who is known for speaking his mind.  “Everyone’s afraid of Amazon,” said Richard Curtis, a longtime agent who is also an e-book publisher. “If you’re a bookstore, Amazon has been in competition with you for some time. If you’re a publisher, one day you wake up and Amazon is competing with you too. And if you’re an agent, Amazon may be stealing your lunch because it is offering authors the opportunity to publish directly and cut you out.  “It’s an old strategy: divide and conquer,” Mr. Curtis said.  Amazon executives, interviewed at the company’s headquarters here, declined to say how many editors the company employed, or how many books it had under contract. But they played down Amazon’s power and said publishers were in love with their own demise.  “It’s always the end of the world,” said Russell Grandinetti, one of Amazon’s top executives. “You could set your watch on it arriving.”  He pointed out, though, that the landscape was in some ways changing for the first time since Gutenberg invented the modern book nearly 600 years ago. “The only really necessary people in the publishing process now are the writer and reader,” he said. “Everyone who stands between those two has both risk and opportunity.”  Amazon has started giving all authors, whether it publishes them or not, direct access to highly coveted Nielsen BookScan sales data, which records how many physical books they are selling in individual markets like Milwaukee or New Orleans. It is introducing the sort of one-on-one communication between authors and their fans that used to happen only on book tours. It made an obscure German historical novel a runaway best seller without a single professional reviewer weighing in.  Publishers caught a glimpse of a future they fear has no role for them late last month when Amazon introduced the Kindle Fire, a tablet for books and other media sold by Amazon. Jeffrey P. Bezos, the company’s chief executive, referred several times to Kindle as “an end-to-end service,” conjuring up a world in which Amazon develops, promotes and delivers the product.  For a sense of how rattled publishers are by Amazon’s foray into their business, consider the case of Kiana Davenport, a Hawaiian writer whose career abruptly derailed last month.  In 2010 Ms. Davenport signed with Riverhead Books, a division of Penguin, for “The Chinese Soldier’s Daughter,” a Civil War love story. She received a $20,000 advance for the book, which was supposed to come out next summer.  If writers have one message drilled into them these days, it is this: hustle yourself. So Ms. Davenport took off the shelf several award-winning short stories she had written 20 years ago and packaged them in an e-book, “Cannibal Nights,” available on Amazon.  When Penguin found out, it went “ballistic,” Ms. Davenport wrote on her blog, accusing her of breaking her contractual promise to avoid competing with it. It wanted “Cannibal Nights” removed from sale and all mentions of it deleted from the Internet.  Ms. Davenport refused, so Penguin canceled her novel and is suing her to recover the advance.
Amazon.com, the online retailer, has long competed with bookstores; now it is starting to make deals with authors, bypassing the traditional publisher.
