I have a situation where there are two completely different works (with different titles) by the same author with the same translated title. In creating the NAR there shouldn't be any problem with 4XXs matching but should there be another way to distinguish them? In addition to the different original titles the 046 $ks would be different. The original works are VERY different: one is a multi-volume comprehensive history of a specific period and the other is a very brief pictorial overview of the entire history such as might be found in a short encyclopedia entry. In addition to the different original titles the 046 $ks would be different. Should I just leave the 2 NARs with matching 4XXs or should I try to distinguish them further? RDA NARs make it pretty clear the expressions represent 2 different works.
