Hi again,

Ignore the email I sent just some hours back: the changes I had made
were should not be necessary for Z3950. It appears the Library of
Congress response to the Z3950 download request is in a different
protocol/format called SRW or SRU. Dr Bainbridge suggests that you use
the same details to connect to the Library of Congress server, but fill
them out in the "SRW" part of the download pane rather than in the Z3950
part.

Other details that you can try to use in this part of the download pane
when trying to connect to the Library of Congress:

Host: http://z3950.loc.gov
Port: 7090
Database: voyager
Find: digital library technologies
Max Records: 2

The above URL and port were the ones originally used by the Library of
Congress for Z3950 and SRW/SRU communication. It still works.

Regards,
Anupama
