Brahmanda Purana
The text was often changed after the 10th-century, and new sections probably replaced older ones. The 13th-century Yadava dynasty scholar Hemadri quoted large parts of the then existing Brahmanda Purana, but these parts are not found in currently surviving versions of the same text. This suggests that the 13th-century version of this Purana was different in many respects than extant manuscripts.
