You're right, we need to add the mappings between 180, 181, 182 and 185
and MADS. That was an oversight.

As for the 111 and 130 records coded as LCSH, there are some name headings
(there are also some in the other name fields) that have non-free floating
subdivisions that are in LCSH. In these cases they are specified in 008/14
as inappropriate as a main or added entry, meaning of course that they can
only be used as subject headings, not name headings. We will add provision
for these in the mapping.

Thanks for finding these errors.
