MARC::Errorchecks -- Collection of MARC 21/AACR2 error checks
Module for storing MARC error checking subroutines,
based on MARC21, AACR2, and LCRIs.
These are used to find errors not easily checked by
the MARC::Lint and MARC::Lintadditions modules,
such as those that cross field boundaries.
Each subroutine should generally be passed a MARC::Record object.
