That didn’t take long. Just days after a judge approved an antitrust settlement between some book publishers and the Justice Department allowing a return of discounted e-books, at least some new-releases are appearing again in e-book form for just $9.99.

Among those benefiting quickly are fans of Michael Chabon, whose new novel “Telegraph Avenue,” was available Tuesday for $9.99 both on Amazon’s Kindle e-bookstore and Apple Inc ’s iBook store. That is well below the $12.99 to $14.99 range at which many new e-books were priced over the past couple of years.

That higher price range will likely still apply for a while to some e-books. Only three publishers settled with the Justice Department, and of those three, only HarperCollins has confirmed it has reached a new agreement with retailers such as Amazon.com Inc . in accord with the settlement. Mr. Chabon’s book, not surprisingly, is a HarperCollins title. Two other major publishers – Pearson PLC ’s Penguin Group (USA) and Macmillan, a unit of Verlagsgruppe Georg von Holtzbrinck GmbH – continue to fight the antitrust suit, as is Apple, another defendant in the suit. (HarperCollins is a unit of News Corp . , which also owns The Wall Street Journal).

It isn’t clear when the other two big publishers that have settled CBS Corp ’s Simon & Schuster Inc. and Lagardere SCA's Hachette Book Group, will reach new deals with retailers. Simon & Schuster declined to comment on the status of its discussions with Amazon. A spokeswoman for Hachette said the publisher was “engaged in productive discussion with e-book distribution agreements to conform our agreements to the terms of the settlement.”

The final judgment entered in court on Friday gave publishers 10 days to take steps to let e-book retailers out of agreements that prevented discounting.
