The purpose of this crosscheck is to prevent records from matching when the items have different titles.

This crosscheck follows the same data extraction rules as for the title as a primary key, with the following exceptions:

• subfield $h (GMD) is ignored
• each retrieved title is truncated to 40 characters

• standard normalization is applied

Results retrieved from the 245 field of each record are compared first; if that fails, the comparison is expanded to include all alternate titles (246) in each record.

• Must match in both records. A missing title fails the match.

Important: unlike the primary key query for TITLE, the title crosscheck does not consider the GMD, so be sure to enable X245H.
