Not easily if they do not provide a Z39.50 server or raw MARC record
download. What you are seeing when looking at the "MARC view" is a
representation of the MARC format that has been designed to be easily
readable for humans. MARC records are actually (usually, anyway) stored in
the binary format that LC provides their records in.

Most libraries that use copy from libraries other than their national
library use OCLC or Skyriver (or a similar union database) for obtaining
records. It would be possible to write screen scrapers to harvest MARC data
from OPACs, but since there is no standard formatting, you would need at
the very least a screen scraper per ILS, if not a screen scraper per
catalog to cope with minor customizations made by various libraries.
