Volumes six and seven of 'The Piers Plowman Electronic Archive (PPEA)' mark a significant achievement for the work of the editors and contributors to the project. The omnibus project aims to provide not only colour digital images of the entire corpus of William Langland’s texts of 'Piers Plowman', from the medieval period through the sixteenth-century, but also electronic transcriptions of each manuscript (as explained by Duggan 2005). Volume six includes images and transcriptions from San Marino, Huntington Library Hm 128 (Hm, Hm2); volume seven includes images and transcriptions from London, British Library MS Lansdowne 398 and Oxford, Bodleian Library, MS Rawlinson Poetry 38 (R). 'Piers Plowman' has traditionally received much scholarly attention, not only due to its status as a canonical poem surviving from the Middle English period, but also because Langland wrote three distinct versions of the poem (A, B, and C), and thus the poem offers much for the study of Middle English textual history, editorial theory, and reception theory
