Findings
Perhaps by making some modifications to UNIMARC, we can meet the
cataloguing requirements of the mostly used information resource in Iran
that is printed book, but due to rapid extension of digital resources
and tendency to use them in Iran, limited capabilities of UNIMARC that
is, not linking to digital resources and not having metadata schemes
such as MARCXML, MODS, METS, and MADS, do not seem to draw a better
future compared to MARC21.
