The world's book trade meets in Frankfurt next week on the brink of a long-feared transformation of the industry for which few are well prepared.

Electronic reading devices like Amazon's Kindle are set to enter the mass market, starting with a surge in sales this Christmas holiday season, helped by lower prices, rising consumer confidence and better distribution outside the United States.

Like the music and newspaper industries before it, the book-publishing world now faces vanishing revenues as sales of physical discs, papers and books give way to far cheaper or free digital distribution.

Meantime, publishers are distracting themselves by fretting over the price of eBooks, withholding eBook releases so as not to cannibalize hardcover book sales, and watching helplessly as their businesses erode in front of them, analyst Sarah Rotman Epps of technology research firm Forrester wrote this week.

Forrester estimates 3 million ereaders will be sold in the United States this year and double that number next year, taking the total sold to 10 million by the end of 2010 -- excluding other digital screens, such as phones and PCs.

There are exceptions in the book industry to the general lack of enthusiasm for all things digital.

Bookseller Barnes & Noble is expected soon to launch its own ereader, which would provide strong competition to the Kindle and Sony's reader in the market for book-sized screens that grab and display text from the Web.

The top U.S. bookstore chain -- America's first bookseller to advertise on television in the 1970s and also the first to discount books -- already has the world's largest online bookstore, which it launched in July.

Barnesandnoble.com sells most of its new releases as ebooks for $9.99, the same as Amazon, and far cheaper than the physical versions in most cases. At launch it had over 700,000 titles readable on a variety of devices like Apple's iPhone.

The company has declined to comment on reports it will soon sell its own wireless touchscreen reading device. We believe readers should have access to books in their digital library from any device, anywhere and any time, a spokeswoman said.

BACK TO LIFE

Most of Barnes & Noble's electronic titles at launch were out-of-copyright books in the public domain supplied by Google, which wants to scan all the world's books and make them available online.

So far, the Internet giant has scanned 10 million books through agreements with libraries and publishers, but it has made enemies along the way by scanning library books without always gaining prior permission from the rights holders.

Now Google seems to be on the verge of settling a mammoth lawsuit with U.S. publishers. A final court hearing takes place on November 9 on the settlement, which would entail Google's helping to set up a books registry to track down and pay rights holders.

The rest of the world -- especially France and Germany -- continues largely to view Google with suspicion. The company is sending its top lawyer to Frankfurt to engage once again with the industry.

Google argues it can help publishers and authors by enabling readers to find works online, especially those that are out of print. For books still in copyright, Google displays text snippets in answer to search queries, and details of retailers.

Books that were previously out of print will come back to life, Santiago de la Mora, Google's head of European print partnerships, told Reuters. There are 1.8 billion Internet users. I'm pretty sure you can find readers for everything.

SCANDAL

More digital content opens the door to easier piracy -- a growing threat from this year's guest of honor at the Frankfurt Book Fair, China.

Despite its huge potential, China has been one of the most difficult markets for global media companies, not only because of strict limitations on their activities there but also as a result of rampant content piracy.

Media baron Rupert Murdoch, speaking at a media forum in Beijing on Friday, called on China to open its tightly controlled media sector, and said governments should clamp down on piracy.

There should be a price paid for quality content and yet large media organizations have been submissive in the face of the flat-earthers who insisted that all content should be free all the time, he said, repeating what has become his mantra.

Organizers of the book fair must tread carefully with the Chinese authorities, whom they have already upset by inviting dissident authors Dai Qing and Lei Ling to a pre-fair symposium, resulting in a walkout by some of the Chinese delegation.

Democracy and freedom of expression always involve friction and the scandal over the weekend was only the beginning of a democratic dispute that lies ahead for Guest of Honor China, the fair's director, Juergen Boos, wrote in an open letter.

The Frankfurt Book Fair runs from next Wednesday to Sunday. Last year's event attracted 300,000 visitors and more than 3,000 exhibitors from about 100 countries.
