In paperback and on iPhone

Christopher Paolini’s “Brisingr,” Philip Pullman’s “His Dark Materials” trilogy and Peter Matthiessen’s award-winning “Shadow Country” are among the dozen-plus books coming to the iPhone and to iPod Touch from publisher Random House Inc.

“We are pleased to be making this initial list of outstanding books by some of our top-selling authors available to a groundbreaking group of readers,” Matt Shatz, Random House’s vice president for digital books, said in a statement this week.

Random House recently announced it was adding thousands of books to its digital catalog and has said that e-sales more than tripled in 2008, although the electronic market remains a tiny part of the overall book market.

Several other publishers, including Simon & Schuster and HarperCollins, have been making e-books available on iPhones.
