On line 924 of cataloguing/addbiblio.pl we have this line: $template->param( title => $record->title() ) if ($record ne "-1" && C4::Context->preference('marcflavour') eq "usmarc"); As far as I know, the 'marcflavour' syspref will never, ever be equal to "usmarc". I'm not sure if this has any practical sideeffects, though, I just spotted it while looking for something else.
