I wonder if anyone here has experiences > with some MARC validation tool for this purpose? Are you talking about low-level structural problems, like the record length field (Ldr/00-05) not matching the actual record length? Or high-level errors, like a 245 field without a subfield $a or an invalid country code? If it's the latter, Bryan Baldus wrote a Perl module (MARC::Lint) that looks pretty comprehensive: https://metacpan.org/release/MARC-Lint It includes a script (marclint) that you can use directly from the command line. If it's the former, I've attached a Perl script I wrote (marcdiag) that catches most low-level errors. It only has one dependency -- Getopt::Long, which is pretty standard but not part of a core Perl installation.
