Today, former president Bill Clinton visits Oprah with his book Giving: How Each of Us Can Change the World (Knopf, $24.95; RH Audio unabridged CD, $29.95), which pubs today. This evening, he’ll appear on Late Night with Dave Letterman.

Authors on yesterday’s Today show:

NBC TV reporter Jay Barbree announced "Live from Cape Canaveral": Covering the Space Race, from Sputnik to Today (Collins, $26.95). PW declared “Barbree writes with infectious enthusiasm about the glory days of space exploration, and his book will be an enjoyable introduction for a new generation and a fond remembrance for boomers.”

Bestseller Kenneth Davis confessed Don't Know Much About Anything: Everything You Need to Know but Never Learned About People, Places, Events, and More! (Harper Paperbacks, $14.95).

Authors on today’s Early Show:

J. Randy Taraborrelli introduced Diana Ross: A Biography (Citadel, $26.95), pubbing today. In its starred review, PW noted “Taraborrelli has totally rewritten, expanded and updated his 1989 bio Call Her Miss Ross to create what is now truly a definitive biography. It's to Taraborrelli's credit that he refuses to cast people as one-dimensional heroes, victims or villains. This riveting page-turner is actually a tribute to a woman who has survived and thrived for more than four decades in a profession littered with one-hit wonders.”

Roger Director, whose memoir is I Dream in Blue: Life, Death, and the New York Giants (Harper, $24.95). PW’s opinion: “Director combines the hangdog obsessive who is an axiom in such books with an otherwise cool veneer of a Santa Monica entertainment veteran.”

On The Diane Rehm Show, Michael Mandelbaum explained Democracy's Good Name: The Rise and Risks of the World's Most Popular Form of Government (Public Affairs, $27.95). PW predicted “readers will find a lucid, accessible blend of history, political science and sociology, with a wealth of fresh insights into the making of the contemporary world.”

Authors on today’s Leonard Lopate Show:

Canadian emergency room physician Vincent Lam with his collection of short stories, Bloodletting & Miraculous Cures. (Weinstein Books, $24.95; Brilliance Audio abridged CD, $26.95). From PW’s starred review: “Winner of Canada's Giller Prize, Lam puts all the sex, and death and sleep deprivation crucial to any hospital drama in his debut story collection about doctors in the making. The stories' quiet strength lies not in the doctors' education but in Lam's portrayal of the flawed humans behind the surgical masks.”

Michael Palin pored over Diaries 1969-1979: The Python Years (Thomas Dunne, $25.95; Audio Renaissance abridged CD, $25.95), which pubs today. A bestseller in the UK last year, the 672-page tome is finally making its US debut today.

Professor Bjorn Lomborg, author of Cool It: The Skeptical Environmentalist's Guide to Global Warming (Knopf, $21), which also pubs today.

Masaharu Morimoto, the Japanese Iron Chef, served up Morimoto: The New Art of Japanese Cooking (DK Adult, $40).

On CNN’s Glenn Beck Show: Staff sergeant David Bellavia, co-author of House to House, (Free Press, $26; Blackstone Audio unabridged CD, $55), about which PW said “Bellavia's account of the fierce 2004 fighting in Fallujah will satisfy readers who like their testosterone undiluted.”
