I suspect this is what StoneWall Brigade was referencing.

As the link indicates there was an apparent plagiarism issue with one of Goodwin’s books, something many of us amateur historians became aware of years ago when the possible issue became public knowledge. I don’t know whether her possible past plagiarism had any impact on the book you chose.
Thanks for the link. The article is dated 2002 and ‘Team of Rivals’ was published in 2005, so hopefully she got her “mechanical processes” straightened out in time for that book.
