On the Today show this morning: Gerald Gardner, co-editor of 80: Our Most Famous Eighty Year Olds Reveal Why They Never Felt So Young (Sourcebooks, $24.95).

Authors on today’s Leonard Lopate Show:

Bestselling Harvard psychology professor Steven Pinker considered The Stuff of Thought: Language as a Window into Human Nature (Viking, $29.95; Penguin Audio abridged CD, $39.95). PW wrote “His vivid prose and down-to-earth attitude will once again attract an enthusiastic audience outside academia.”

Brooklyn District Attorney Charles Hynes, whose debut crime novel is Triple Homicide (Thomas Dunne, $24.95), discussed this weekend’s Brooklyn Book Festival.

Encore interviews on Tavis Smiley tonight:

Former U.S. Marine captain Brian Steidle, author of The Devil Came on Horseback: Bearing Witness to the Genocide in Darfur (PublicAffairs, $27.95. Blackstone Audio unabridged CD, $19.95), which PW called an “impassioned memoir… Steidle's personal and fluent account effectively channels an idealistic, adventuresome young man's growing frustration and horror in the face of ongoing crimes against humanity and international complacency.”

Eddie Levert, co-founder of the R&B group The O'Jays and co-author—with his late son, Gerald—of I Got Your Back: A Father and Son Keep it Real About Love, Fatherhood, Family, and Friendship (Harlem Moon, $18.95).

Authors on Book TV this weekend:

Former President Bill Clinton discusses Giving: How Each of Us Can Change the World (Knopf, $24.95; RH Audio unabridged CD, $29.95).

Former Clinton adviser Dick Morris expresses Outrage: How Illegal Immigration, the United Nations, Congressional Ripoffs, Student Loan Overcharges, Tobacco Companies, Trade Protection, and Drug Companies Are Ripping Us Off… And What to Do About It (HarperCollins, $26.95).

Middle East historian Raymond Ibrahim interprets The Al Qaeda Reader (Broadway, $15.95).

Conservative pundit Michael Ledeen observes The Iranian Time Bomb: The Mullah Zealots' Quest for Destruction (Truman Talley Books, $24.95). PW’s review had this to say: “Ledeen argues passionately for a bolder, better-reasoned American policy toward the Islamic republic. While he may overestimate the potential for regime change in the near future, Ledeen's suggestions merit further discussion.”

On CBS Sunday Morning, Marc Freedman will discuss Encore: Finding Work that Matters in the Second Half of Life (PublicAffairs, $24.95).
