The MARC records are first converted to MODS before being displayed.
For an example, see
http://demo.gapines.org/opac/en-US/skin/default/xml/rdetail.xml?r=12786&l=1&d=0

The raw MARCXML for this record is visible at
http://demo.gapines.org/opac/extras/supercat/retrieve/marcxml/record/12786

The MODS version of this record is visible at
http://demo.gapines.org/opac/extras/supercat/retrieve/mods/record/12786
- note that the 650$x of "N.T." has been converted to "N.T" (stripping
the punctuation) for the heading "Bible Stories, English". This is a
result of the standard MARCXML-to-MODS XSL stylesheet distributed by
the Library of Congress.

I haven't worked out exactly how the "N.T" gets appended directly to
the "Bible" with no intervening space, but my guess is that it's an
XPath expression in OpenILS/Utils/ModsParser.pm that blindly
concatenates the contents of the first XML element within the
<subject> array rather than recognizing that the first XML element, in
this particular case, is composed of two child elements.

Yep, everyone else does. Which is good and bad, I suppose :)

No solution yet, but now that you've pointed out the problem and we
found a reproducible test case, it certainly will help narrow down a
solution.
