In general I would agree that trying to show the user the underlying  
structure of the catalog/subject headings is a bad idea. Another  
problem (with using the authority records/connection) is that you make  
it look like everything is authorized, and it usually isn't. This  
leads to queries that are too narrow and that misses some records. The  
same problem arrises when searching "through" the authority index.

In LIBRIS we simply index the 4XX in the authority records with the  
bibliographic record. That way the user does not have to know the  
preferred term, or what a preffered term is, or that there is such a  
thing as an authority record. Ofcourse this only works with authorized  
records, but it is better than nothing.
