The E Pluribus Unum Project is "an online archive designed for the use of students, teachers, and other researchers who wish to examine the attempt to make "one from many" in three critical decades of American life: the 1770s, the 1850s, and the 1920s. [...] Resources are arranged in topical clusters. Each set of materials typically includes: an introductory essay; questions for discussion, writing, and research; and sets of resources (including e-texts, digitized artifacts, and links) to facilitate online research. Sample student exhibits are also displayed. [...] In addition to the topical clusters, an extensive listing of links to online versions of printed works and speeches published in America in the 1850s is provided here in order to promote in-depth research. Similar listings for the 1770s and 1920s will be available in the future."
