Adam, my recollection is that this was not something implied in RLIN, 
where the cataloger could access multiple records for the same 
manifestation within a given "cluster,"  and the heading in one 
record in the cluster could have a date while another record in the 
cluster might not. In that situation there was no obligation to cite 
the specific library that contributed the record just because one was 
basing the authority record on the same manifestation. An analogy in 
OCLC would be institutional records. In the OCLC environment, would 
we really want to cite a specific institutional record if there was 
only one work in the database by an author but multiple institutional 
records associated with it and only one of the records had a heading 
with the date?
