Hey, and it occurs to me, in an HTML display, it might be better to use
an actual em-dash than the traditional two hyphens too? Since the LC
documentation just talks about "dash" -- two hyphens is how you
approximate an em-dash in ascii of course, but we're not living in ascii
anymore!

Only for certain subfields:
Dash (-) that precedes a subdivision in an extended 600 subject
heading is not carried in the MARC record. It may be system generated
as a display constant associated with the content of subfield $v, $x,
$y, and $z.

Hi all, I'm writing some marc record display code, and I have a
question about the 'right' way to display LCSH headings.
LCSH headings are typically displayed with "--" between components.
But looking at the MARC, it looks like the "--" punctuation isn't
actually in the MARC field. (A rare instance where display
punctuation isn't in the marc!).
Is it correct for any LCSH 6xx field (which you know because the 2nd
indicator is 0, right?), to add "--" between ALL present subfields
on display? Do I have the right logic there?
Thanks for any advice!
