The Routledge Companion to Transnational American Studies provides scholars and students of American Studies with theoretical and applied essays that help to define Transnational American Studies as a discipline and practice.

In more than 30 essays, the volume offers a history of the concept of the "transnational" and takes readers from the Barbary frontier to Guam, from Mexico's border crossings to the intifada's contested zones. Together, the essays develop new ways for Americanists to read events, images, sound, literature, identity, film, politics, or performance transnationally through the work of diverse figures, such as Confucius, Edward Said, Pauline Hopkins, Poe, Faulkner, Michael Jackson, Onoto Watanna, and others. This timely volume also addresses presidential politics and interpictorial US history from Lincoln in Africa, to Obama and Mandela, to Trump.　

The essays, written by prominent global Americanists, as well as the emerging scholars shaping the field, seek to provide foundational resources as well as experimental and forward-leaning approaches to Transnational American Studies.
