Comparison of IranMARC Manual (for monographs), MARC21 & UNIMARC with 17 identified problems related to IranMARC

Due to UNIMARC is the basis for the IranMARC format، in this paper all 17 problems identified by Kokabi in 1994 about adoption of UNIMARC in Iran، were compared with IranMARC Manual to find the suggested solutions for them. Because of the international role of MARC21 and UNIMARC، these 17 problems were checked out to reveal if these problems are solved in last update of UNIMARC and if there is any solution for them in MARC21. Eventually with these findings، researchers determined that MARC21 has more adaption with special feature of Persian cataloging and bibliographic features.
