He's written million-selling books about his early years and the meaning of public life. Now, Sen. Barack Obama, with the help of his campaign staff, has another side to share with readers: policy wonk.

"Change We Can Believe In: Barack Obama's Plan to Renew America's Promise" is coming out Sept. 9 as a paperback with an announced first printing of 300,000 copies and a list price of $13.95. Looking ahead to the digital market, the e-book, also $13.95, will go on sale the day before.

The book will include a foreword by Obama, the Democrats' presumptive presidential nominee, and feature sections — written by members of Obama for America, his presidential campaign — on such issues as health care, energy and national security. "Change We Can Believe In" also compiles some of his better-known speeches, including his celebrated talk on race and his recent address in Berlin.
