Hi there, the bug is in OLDnewbiblio in Biblio.pm at line 1459 (version 2.0.0pre5) To fix, replace : $sth->execute($bibnum,$biblio->{'title'},$biblio->{'author'},$biblio->{'copyright'},$series,$biblio->{'seriestitle'},$biblio->{'notes'},$biblio->{'abstract'}); with : $sth->execute($bibnum,$biblio->{'title'},$biblio->{'author'},$biblio->{'copyrightdate'},$series,$biblio->{'seriestitle'},$biblio->{'notes'},$biblio->{'abstract'}); Chris
