Gerald Posner Plagiarized in Why America Slept and Secrets of the Kingdom, Research Shows

In this week's Miami New Times, we write about new evidence that Gerald Posner plagiarized dozens of passages in his 2003 book Why American Slept and in 2005's Secrets of the Kingdom. After the jump, you can check out all the proof. But first, a little background:

Back on March 16, Miami New Times first published evidence that the Miami Beach writer Gerald Posner had plagiarized eight sections in his 2009 book Miami Babylon from Frank Owen's 2003 work, Clubland.

Posner, the author of 11 books including a Pulitzer finalist, had already resigned from the Daily Beast website after stories by Slate's Jack Shafer proved he'd lifted material from the Miami Herald and elsewhere.

Then, with the help of Greg Gelembiuk, a doctoral student who began researching Posner's work after Shafer's first story, we published on April 1 another 16 instances of stolen text in Miami Babylon.

Posner has offered a variety of defenses. He apologized after Shafer's stories and blamed the "warp speed of the Net" for screwing up his Beast stories. He told us this past May 16 that a new system of "trailing endnotes" may have caused problems in Babylon. By our third story, Posner said there was a "concerted effort" afoot to "discredit" his work.

Now comes new evidence, again courtesy of Gelembiuk. The 48-year-old Wisconsin student purchased ebook copies of Why America Slept and Secrets of the Kingdom, and ran them through Viper, a free online plagiarism software.

The program found Posner had taken from 24 sources in the two books. Most egregious seems to be his theft from a 1998 book by David Hoffman called The Oklahoma City Bombing and the Politics of Terror. Posner appears to have lifted three passages from the book totaling 927 words in Why America Slept.
