1. A computer-implemented method for correcting textual errors in digital volumes in a corpus, the method comprising: receiving a plurality of candidate volumes comprising a basis volume and a plurality of comparison volumes; comparing the basis volume with the plurality of comparison volumes to identify identical sequences of text that are identical across all of the plurality of candidate volumes and mismatched sequences of text that contain different text in different candidate volumes; resolving at least some of the mismatched sequences by comparing the different text in the different candidate volumes to ascertain correct text for the mismatched sequences by: determining a type of mismatch for a given mismatched sequence that contains different versions of text in different candidate volumes; and applying a resolution technique to the given mismatched sequence selected responsive to the type of mismatch; and correcting errors in the plurality of candidate volumes using the ascertained correct text.

The method of claim 1 , further comprising: determining a proportion of text that a comparison volume of the plurality of comparison volumes has in common with the basis volume; and filtering the comparison volume of the plurality of comparison volumes out of the plurality of candidate volumes responsive to the proportion of text being below a specified threshold proportion.
