Bearing in mind that content may come from any source, there are cases where publishers may indeed be "authority controlled" (though not via library-supplied metadata). Publisher-supplied metadata (ONIX for Books) may include publisher identifiers drawn from a variety of standardized code databases, such as GLN, SAN, ISNI, as well as library authority metadata (LCCN) (See ONIX Code List 44). Such metadata (and authorities) may be linked to a BIBFRAME Instance via a common ISBN.

Stephen, Thanks.

can you say more about the circumstances, and if this authorized heading 
is *in addition to* the transcribed publisher statement? If it is 
something that is quite rare, then maybe it shouldn't be used as an 
example in the simple view of the model. I'm guessing that it can be 
used as a subject (a book about the Aldine Press, for example) and 
possibly as a corporate body creator. With the role "pub" my guess is 
that it would be used mainly for rare books where the publisher itself 
is of interest (Aldine Press again).

? I'm unclear on what you mean here. MARC expresses "subject" by coding 
data in a 6xx field, no? Or do you mean that MARC can't specify that the 
6xx relates to work? (Which, since in FRBR/RDA subjects *only* relate to 
work is unambiguous.)

I agree that if the term "authority" is used differently in the bibframe 
model then it will be confusing. The definition in the model is:

"BIBFRAME Authorities are key authority concepts that are the target of 
defined
relationships reflected in the Work and Instance. Example of BIBFRAME 
Authority
Resources include People, Places, Topics,
Organizations, etc. From a cataloging
perspective Authorities provide a means for
supporting disambiguation and synchronization
around authoritative information. From a users
perspective, BIBFRAME Authorities provide
effective and efficient control points that can be
used to help navigate and contextualize related
BIBFRAME Works and Instances."

It's unfortunate that it defines authorities as "key authority concepts" 
-- so maybe it does need further unpacking. In particular, there is the 
question about controlled lists v. authorities. They both fit nicely 
into SKOS but we haven't treated them as being "same" for cataloging 
purposes in the past. As we move away from headings defined as text 
strings, the difference between authority control and vocabulary control 
will probably diminish, and I believe that both LC and OCLC have 
pondered this when working with name authority files. For this reason it 
is even more important to clarify what we mean by BIBFRAME Authority.

If you have a spare hour or so, start here:

and follow the thread (which you may have followed originally, but 
reading through it definitely refreshed my memory)
This is a thread about FRBR and aggregates, and I believe that we still 
have a serious problem with how this is modeled in FRBR, and also in 
RDA. I am going to try to write a summary of what was said on that 
thread, but it may take a while.
