Currently, the OPAC "cite" feature only displays the MARC21 author 100$a, 110$a, 111$a, 700$a, 710$a and 711$a subfields. However, it is standard MARC21 cataloguing practice to also fill in the 110$b and 710$b subfields - as well as the 111 and 711 $b, $c, $d and $n subfields. The "cite" feature should display the information saved in these other subfields.
