After LBJ's retirement in 1969, Goodwin taught government at Harvard for ten years, including a course on the American Presidency.
In 1977, her first book was published Lyndon Johnson & the American Dream, drawing on her conversations with the late president. This book became a New York Times bestseller and provided a launching pad for her literary career.
Goodwin was the first female journalist to enter the Boston Red Sox locker room. She consulted on and appeared in Ken Burns' 1994 documentary Baseball.
Goodwin won the Pulitzer Prize in 1995 for No Ordinary Time: Franklin and Eleanor Roosevelt: The American Homefront During World War II. Goodwin received an honorary L.H.D. from Bates College in 1998.
Goodwin won the 2005 Lincoln Prize (for best book about the American Civil War) for Team of Rivals, a book about Abraham Lincoln's Presidential Cabinet. She is currently a member of the Abraham Lincoln Bicentennial Commission advisory board.
Since 1997 Goodwin has been a member of the Board of Directors for Northwest Airlines.
In a March 24, 2002, interview with the Associated Press, McTaggart said, "If somebody takes a third of somebody's book, which is what happened to me, they are lifting out the heart and guts of somebody else's individual expression."
Once this was made public — and the almost identical phrases in Goodwin’s book were placed in numerous newspaper and magazine articles side by side with the originals in question — Goodwin admitted that she had previously reached a large "private settlement" with McTaggart over the issue.
An August 2002 Los Angeles Times story by Peter King reported that there were many passages in Goodwin’s book on the Roosevelts ("No Ordinary Time") that were apparently lifted directly from Joseph Lash’s "Eleanor and Franklin" and Hugh Gregory Gallagher’s "FDR’s Splendid Deception," as well as other books. (See Timothy Noah, "Historians Rewrite History: The Campaign to Exonerate Doris Kearns Goodwin," Slate online, Nov. 13, 2003.) The claims of plagiarism have damaged her reputation; however, many in the academic, literary, and entertainment communities have continued to support her and her assertion of innocence. As in the case of Stephen Ambrose, the extensive use of research assistants has been identified as a possible source of this uncredited use of other writers' work.
Goodwin revealed in her contributions to Ken Burns' award-winning documentary film Baseball her life-long support of both the Brooklyn Dodgers and the Boston Red Sox.
