AUTOMATED CLEANUP OF DIGITAL VOLUMES

Textual errors in digital volumes in a corpus are corrected by comparing a set of similar digital volumes, the set including a basis volume and a plurality of comparison volumes. The basis volume is compared with the comparison volumes to identify sequences of text that are identical across all of the candidate volumes and mismatched sequences of text that contain different text in at least one of the candidate volumes. The correct text for at least some of the mismatched sequences is resolved by comparing the different text in the different candidate volumes. The mismatched sequences are replaced by the resolved correct text, thereby correcting errors in the candidate volumes.
