President Bush's vacation is shorter this year, and so is his reading list.
As he did last year, Bush took three history books along to his Texas ranch. But in 2005, Bush planned a whole month away from the White House and had 1,500 pages of reading to fill his time. This year, with just 10 days of break time, the president took about 1,000 pages worth.
Two of the books were about Republican Party hero Abraham Lincoln — "Lincoln: A Life of Purpose and Power," by Richard Carwardine, and "Lincoln's Greatest Speech: The Second Inaugural," by Ronald C. White Jr.
His third choice, "Polio: An American Story," by University of Texas historian David M. Oshinsky" won the Pulitzer Prize.
It tells the story of polio in the United States in the 1940s and 1950s, including the establishment of the March of Dimes and the discovery of the Salk and Sabin vaccines.
