The ethnically diverse scope, broad chronological coverage, and mix of biographical, critical, historical, political, and cultural entries make this the most useful and exciting poetry reference of its kind for students today. American poetry springs up out of all walks of life; its poems are "maternal as well as paternal...stuff'd with the stuff that is coarse and stuff'd with the stuff that is fine," as Walt Whitman wrote, adding "Of every hue and caste am I, of every rank and religion." Written for high school and undergraduate students, this two-volume encyclopedia covers U.S. poetry from the Colonial era to the present, offering full treatments of hundreds of key poets of the American canon. What sets this reference apart is that it also discusses events, movements, schools, and poetic approaches, placing poets in their social, historical, political, cultural, and critical contexts and showing how their works mirror the eras in which they were written. Readers will learn about surrealism, ekphrastic poetry, pastoral elegy, the Black Mountain poets, and "language" poetry. There are long and rich entries on modernism and postmodernism as well as entries related to the formal and technical dimensions of American poetry. Particular attention is paid to women poets and poets from various ethnic groups. Poets such as Amiri Baraka, Nathaniel Mackey, Natasha Trethewey, and Tracy Smith are featured. The encyclopedia also contains entries on a wide selection of Latino and Native American poets and substantial coverage of the avant-garde and experimental movements and provides sidebars that illuminate key points.

In September 1776, two men from Connecticut each embarked on a dangerous mission. One of the men, a soldier disguised as a schoolmaster, made his way to British-controlled Manhattan and began furtively making notes and sketches to bring back to the beleaguered Continental Army general, George Washington. The other man traveled to New York to accept a captain's commission in a loyalist regiment before returning home to recruit others to join British forces. Neither man completed his mission. Both met their deaths at the end of a hangman's rope, one executed as a spy for the American cause and the other as a traitor to it. Neither Nathan Hale nor Moses Dunbar deliberately set out to be a revolutionary or a loyalist, yet both suffered the same fate. They died when there was every indication that Britain would win the American Revolution. Had that been the outcome, Dunbar, convicted of treason and since forgotten, might well be celebrated as a martyr. And Hale, caught spying on the British, would likely be remembered as a traitor, rather than a Revolutionary hero. In The Martyr and the Traitor, Virginia DeJohn Anderson offers an intertwined narrative of men from very similar backgrounds and reveals how their relationships within their families and communities became politicized as the imperial crisis with Britain erupted. She explores how these men forged their loyalties in perilous times and believed the causes for which they died to be honorable. Through their experiences, The Martyr and the Traitor illuminates the impact of the Revolution on ordinary lives and how the stories of patriots and loyalists were remembered and forgotten after independence.
