RDA 5.1: Conference Place Names (X11)
Conference place names
In AACR2, multiple place names in an X11 were separated by a comma and the word and. In RDA, a semi-colon is to be used instead:
original field: 111 2_ $a Anglo-Dutch Historical Conference $n (2nd : $d 1962 : $c Utrecht, Netherlands, and Amsterdam, Netherlands) updated field: 111 2_ $a Anglo-Dutch Historical Conference $n (2nd : $d 1962 : $c Utrecht, Netherlands; Amsterdam, Netherlands)
