Mr. Cheney’s memoir, which will focus on the past 40 years of his life, mostly in Washington, will be published in the spring of 2011. The deal was negotiated by Robert Barnett, a Washington lawyer who also represents Mr. Bush, former President Bill Clinton and President Obama.

The former vice president is working with his eldest daughter, Liz Cheney, on the memoir. Ms. Cheney is helping with research and “filling in the gaps.”

“He’s a student of history, and I think he never really planned to write a book,” Ms. Cheney said. “But I think because the job he just finished is obviously his last job he’ll ever have in government and because he cares about history and has been part of so many consequential events over the last 40 years, he wants to make sure that his story is told, and told in a way that his grandchildren will be able to understand and appreciate even 20 or 30 years from now.”

She said Mr. Cheney had been writing out his thoughts in longhand but had also begun writing on a laptop, working in homes on the Eastern Shore of Maryland, in Virginia and in Wyoming.

In addition to covering his roles in the administrations of Presidents Richard M. Nixon, Gerald R. Ford, George Bush and George W. Bush, Mr. Cheney will write about his private-sector experience, including his time as chief executive of the Halliburton Company, the oil field services provider.
