Here you will find a library of 11 primary texts written by the American philosophers featured on the Timeline. Here is also a brief, annotated bibliography of the very best secondary readings on these thinkers. The primary texts are unabridged and have been carefully selected and annotated to assist students in tracing the development of ideas across thinkers and periods. The material is placed in social, historical, and geographical contexts on the Timeline. See the Lesson Plans page on the site for examples of how to use these texts in your own courses. We invite you to submit your own lesson plans for possible inclusion on this site. To do so, please contact Jennifer Gurley directly at
