Hi Barbara,

I think the max records field in the Z3950 Download panel of your
snapshot looks correct, but I believe the other fields you filled in are
not. There are specific values for host, port and database that one
needs to fill in for each Z3950 server. Since I didn't know what these
are for your question either, in the case of the Library of Congress, I
resorted to searching for Google on the words: library of congress
z39.50 port
Which led to this helpful link: http://www.loc.gov/z3950/lcserver.html

Since it seems you want to download MARC records, I used the information
in the above link to fill in the Z3950 Download fields as follows:

Host: http://lx2.loc.gov
Port: 210
Database: LCDB_MARC8
Find: digital library technologies
Max Records: 2

Unfortunately, while the above information is correct, the Library of
Congress is now returning information in XML format, which the
Greenstone code that retrieves data using the Z3950 protocol did not
anticipate. It is therefore broken at present and will not work, despite
correctly filling in the fields as above. I am in the process of
(hopefully) fixing it.

Thanks for bringing this bug to our attention.

of your suggestion please?
Your snapshot shows that the maxdocs field has the right value (2) for
testing. Are the other settings perhaps what's causing the trouble
downloading? Have you confirmed that the Z3950 port of the LoC is indeed
called "marc"? Have you tried other Z3950 clients and were they able to
download from LoC using the details you filled in into Greenstone's
Download pane?
