Thank you for lot of responses. I customized data entry fields in cataloguing using the following method, http://ksrcas.pbworks.com/w/page/3809371/editingmarcframework When I imported records using following commands, records are display properly. cd /usr/share/koha/bin/migration_tools perl bulkmarcimport.pl -d -commit 1000 -file /home/koha/marcfilename.mrc When I enter records manually and import manually, MARC Veiw display has problem. I am sure, my biblio data is in good condition. Any idea about my problem? -- Vimal Kumar V.
