This is going to be tricky. AFAIK, you can't modify the call number result
table on the fly without proxying since Mil doesn't let you get at the
routine that renders the call numbers.
If proxying is not what you had in mind and rendering the call number
meanings above the table is acceptable, I suppose you could load a
puts a call number explanation somewhere near the top. One trick you could
use if you wanted it lower is to redefine an image in WWWOPTIONS that
contains embedded HTML that renders your value dynamically. As far as I
remember, you can break out of image definitions simply by adding a double
quote, closing the tag, and inserting whatever script you want, e.g.:
BUT_WHATEVER=/screens/image.gif" alt="whatever" border="0"
/></a><script.... [load or embed whatever you like]...</script><img
(note lack of closing quote -- don't forget you broke out of an image tag)
As far as a method for getting the data goes, your best option would be to
download the linked data from id.loc.gov and extract the ranges which could
be processed as strings matched by regex rather than linked data. All
processing could be offloaded on the client.
But this is horribly hacky and a lot of work for relatively little gain.
When you get right down to it, the only purpose of a call number is to
physically collocate materials on the shelf and it's not really that useful
for search which is why practically no one aside from a few cataloging
nerds do call number searches. Plus, anyone geeky enough to do a call
number search actually must know what call number range is relevant to
their needs. Keep in mind that in many cases, no decent call number exists
for a concept and the best one available really is quite crummy so
prominently displaying that won't necessarily be a good thing.
