XSLT file in UNIMARC display the 328$a (thesis note). But in Sudoc network, we fill the 328 field using other subfields (http://documentation.abes.fr/sudoc/formats/unmb/zones/328.htm) So the display of 328 field must be improved. Additionnaly, the thesis national number in 029 could be managed, but maybe it is a french only field... M. Saby
