MARConvert handles special problems or unusual requirements in converting records into or out of MARC21, UNIMARC, or MARCXML bibliographic or authority formats. It will also convert MARC records from one character set to another.
MARCView provides a user-friendly way to view, search, and print ANSI/ISO standard MARC records, UNIMARC records, and MARCXML records. It will also handle many files that are not strictly MARC. (It cannot be used to edit MARC records.)
