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.<br>
<br>
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.<br>
<br>
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.<br>

<p class=MsoNormal>Part of this afternoon, I've been reading the FAQ on the
LCCN Permalink (see <a href="http://lccn.loc.gov/lccnperm-faq.html">http://lccn.loc.gov/lccnperm-faq.html</a>).
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 $z of the 010.<br>
<br>
You are right though, Nina, that there will be resources that even LC won't
have (or won't have an online bib record for). The latter is very real. (No, we
are not done with recon!) So in those cases, it would have to be some other
institution's record.<br>
<br>
I suppose the instruction for the 510$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. <br>
<br>
Can anyone think of any unforeseen problem with this?<br>
