[DCRM-L] ESTC and the revision of SCF [SPAM *32.500]

[Robert Maxwell]

ESTC is an example of such a database, I think, though the URLs for individual items are rather unwieldy and I don’t know if they’re persistent or not. (I’m just copying the MARC record directly from ESTC except for the 510):

Yes, the specification in MRAC 21 will be open-ended about the wort of identifier that may be included.  This will parallel the specification in other fields where subfield $u has been defined.  MARC doesn't try to restrict usage.

However, as I pointed out in my last message, I think that records that we contribute to shared cataloging databases should use links that are as widely applicable as possible -- to publicly available resources through persistent and public identifiers.  However, that is an application guideline, not something that would be in the MARC specifications.

One thing that occurred to be after I sent my last message was the sequence of subfields.  In Elizabeth's example, the URL is for the Evans bibliography as a whole and so it comes between subfield $a and $c.  However, I could imagine a case in which the bibliography is available online and the URL could point to the particular item; in that case, the subfield $u would follow $c.  Can anyone think of an example of this that doesn't involve a proprietary database?  I'd like to include an example in the MARC change proposal, and I don't want to include something that requires a subscription to access.

Part of this afternoon, I've been reading the FAQ on the LCCN Permalink (see http://lccn.loc.gov/lccnperm-faq.html). While the 510$u's URL doesn't have to be the LCCN Permalink, I think it might be simpler to reference it since it should be stable. Notice that the permalink program searches both $a and $z of the 010.

You are right though, Nina, that there will be resources that even LC won't have (or won't have an online bib record for). The latter is very real. (No, we are not done with recon!) So in those cases, it would have to be some other institution's record.

I suppose the instruction for the 510$u could be left open ended, and those who chose to use the LCCN Permalink could, and those who chose to use their institution's (or another institution's) bib record of the resource could do that too.

Can anyone think of any unforeseen problem with this?

I like it. Here's a question, though: Does it matter what URL we provide in the 510 $u? In other words, it might be preferable to include the link to my institution's copy of Evans rather than LC's copy. But then what happens if my institution doesn't have a copy of the reference?

I realize this is in its preliminary stage, but it's something to consider.
