There are known sources which prohibit linking to the online source, e.g. HBR, so if possible could the referred status for this source be flagged so that when rolling over digitisations only , we do not need to have to select 'source from print copy' as we are unable to source from electronic or link to electronic sources. Our annual rollover of digitisations would be vastly streamlined if TADC knew that we couldn't link to the electronic source so therefore did not ask.
