Although none of the manuscripts is believed to be produced by the original author, several date from the first half of the 13th century. The first complete edition edited by Morton in 1853 was based on the British Library manuscript Cotton Nero A.xiv. Recent editors have favoured Corpus Christi College, Cambridge MS 402 of which Bella Millett has written: "Its linguistic consistency and general high textual quality have made it increasingly the preferred base manuscript for editions, translations, and studies of Ancrene Wisse." It was used as the base manuscript in the critical edition published as two volumes in 2005–2006. The Corpus manuscript is the only one to include the title "Ancrene Wisse".
