Adam,
Nate asked me to respond to the excellent point you raise about 655’s with 2nd indicator 0.
A 2nd indicator of ‘0’ in a 655, means that the term came from the LCSH file. My understanding of current practice is that if there is no 155 authority term available, then an appropriate 150 term may be used as a 655 in a bibliographic record. So, if our system matches a 655 _0 to a LCSH subject term, it would be considered valid, and we would return the LCSH subject record.
Everyone’s systems are different and I can see that not everyone would want subject authority records for genre/form terms. If our default process doesn’t work for you, we can offer options based on individual institutions’ needs. For instance, you could choose not to have the 655_0 matched against the LCSH at all. Or we could match them, but not return the subject authority records.
655’s with 2nd indicator values other than ‘0’ (or 7 and $2lcgft) will be matched against the file indicated in the $2 as always, according to the client’s profile. Profiles may always be changed with your project manager.
We appreciate your comments and would welcome any other suggestions, questions, or comments that you may have.
Regards,
Karen Anderson
Nate,
655 headings with other 2nd indicator and $2 subfield values will be processed as they are currently per client
profile.
My understanding is that all of the existing 155 authority records that are currently coded with second indicator 0 in bib. records will be cancelled and new authorities with prefix gf will replace them. Therefore, you will not have any LCSH genre authorities to match on, so you won't be able to return authorities for any terms that aren't in LCGFT. Unless I am misunderstanding, and what you are saying is that you will actually match against LCSH authorities. But if that is the case, what can you return in the way of a genre authority?
For example, let's say we send a bib. record that has this:
655 _0 Science fiction poetry.
There is not currently a 155 authority for this, and so there will not (at least in the short term) be an LCGFT authority for it. So you have nothing to match on there. But you could match against LCSH:
150 Science fiction poetry.
But what could you return to us in that case, since all there is is a subject authority, not a genre authority?
