Krampner's first book, The Man in the Shadows: Fred Coe and the Golden Age of Television, a biography of television producer Fred Coe, was published in 1997. A second, Female Brando: The Legend of Kim Stanley, followed in 2006 by and charted the life of the Broadway actress Kim Stanley.
His most recent nonfiction book, Creamy and Crunchy: An Informal History of Peanut Butter, the All-American Food was published in 2012. The book is a popular history of peanut butter. He is currently working on a biography of screenwriter Ernest Lehman.
Krampner is also the author of short stories, including The Provence Lane Haunting (2002), The Mazeroski Blues (2016), and "Why I Built My House the Way I Did" (2017).
Krampner’s collected papers, consisting of research notes, interview transcripts and audiotapes and general material, are held in the special collections department of the Heard Library at Vanderbilt University in Nashville, Tennessee.
In its review of The Man in the Shadows, Publishers Weekly wrote, "Krampner weaves Coe’s story with solid writing, subtle humor and a slavish devotion to detail." Time called it "engrossing" and TV Guide, "valuable."
Female Brando was described by Talkin’ Broadway as "a must-read for anyone interested in actors and the Golden Age of American Theatre. It is well researched, [...] includes extensive and detailed notes, and is generally fascinating.” The New Yorker said it was "crucial", while Kirkus Reviews said it presented "a steadily turning kaleidoscope of vivid, unsettling images."
