Development efforts update:
DaltonST posted two older versions of Library Codes using the Classify API, and I am dissecting them in order to replace the deprecated Classify lookup with an alternative using SearchRetrieve(over)Url interface language at the Library of Congress SRU server.
I have roughed out two working scripts that return LCCN (card catalog entries) and Dewey and Library of Congress classification codes from fields '010', '050', and '082' of the MARC21 specification implemented in marcxml at the permalink "http://lccn.loc.gov/[LCCNgoeshere]/marcxml" and now I have to process the subject fields found in the '65x' fields. I may end up parsing MODS instead to make my life easier.
I'm trying to recover the VIAF and FAST functionality from the subject and name authorities file at the library of congress name and subject authority databases on the SRU servers.
