NEW YORK, July 10 (Reuters) - A new book by former U.S. President Bill Clinton, called "GIVING: How Each of Us Can Change the World," will go on sale in September, the publisher announced on Tuesday.

Clinton plans to donate a portion of the proceeds to charities and nonprofit organizations, Knopf Publishing Group said.

"GIVING" goes on sale on Sept. 4, with a first printing of 750,000 copies, said Knopf, a division of Random House, which is part of Bertelsmann AG.

Clinton, who recently hit the campaign trial on behalf of his wife, Democratic presidential hopeful Sen. Hillary Clinton, plans a U.S. tour to promote the book, the publisher said.

Clinton, who was elected U.S. president in 1992 and served two terms, lately has spent time building up his charitable Clinton Foundation, which works to address global health, poverty, environmental and economic concerns.

"I've done my best in this book to demonstrate what I've seen firsthand through my foundation's work in Africa and around the world," Clinton said in a statement.

Looking at the charitable work of individuals and nongovernmental organizations "has proven to me that almost everyone -- regardless of income, available time, age and skills -- can do something useful for others and, in the process, strengthen the fabric of our shared humanity," he said.

The book will examine the life-changing aspects of giving, the role of governments, and outline ways ordinary people can make a difference, Knopf said.

Knopf also published Clinton's memoir, "My Life," in 2004, which has sold more than 2 million copies in the United States. That book, which has been printed in more than 30 countries, set a first-day nonfiction sales record of 400,000 copies.
