The Piers Plowman Electronic Archive, a collaborative open-access project, presents the rich textual tradition of Piers Plowman, a fourteenth-century allegorical dream vision attributed to William Langland. Three distinct versions of the poem (A, B, and C) survive in more than 50 unique manuscripts, none in Langland's own hand. The Archive enables instructors, students, and researchers to explore late medieval literary and manuscript culture through the many variations of Piers Plowman. The long-term goal of the project is the creation of a complete archive of the medieval and early modern textual tradition of Langland's poem. The project began at IATH and is now housed at North Carolina State University.
