The injunction prohibits Gawker from "continuing to distribute, publish or otherwise transmit pages from the book" pending a hearing on Nov. 30.
HarperCollins Publishers had sued Gawker after it published images on Nov. 17 from Palin's book before its release next week.
In response, Palin tweeted, "Isn't that illegal?"
Gawker defended its action in a post Thursday titled "Sarah Palin is Mad at Us for Leaking Pages From Her Book" and addressed a message to "Sarah" telling her to read pages about fair use under copyright law. "Or skip the totally boring reading and call one of your lawyers," the post said. "They'll walk you through it."

Gawker Media LLC couldn't immediately be reached for comment Saturday but appeared to have removed the images from its site. (Continues here)
