"America in Modern Times (Since 1890)" brings together the strengths of a political historian (Brinkley) and a specialist in intellectual, social and women's history (Fitzpatrick). The book reflects these areas of expertise in its extensive attention to women's history, social developments, the history of ideas, as well as political history and foreign policy.

This history of post-1941 America draws on social history, women's history, history of ideas, as well as traditional political and foreign policy history. Oral history and first-hand accounts are used to integrate the voices of ordinary Americans into the narrative.
