Hello everybody, I am strugling with koha and Z39.50 servers for a while now. Apparently no server except UNIV OF NORTHERN WALES 147.143.2.5:210 INNOPAC worked for me. So I decided to write a simple program in perl to test the Z39.50 functionality. After solving problems revealed here: http://lists.indexdata.dk/pipermail/net-z3950/2003-October/000356.html and here: http://lists.indexdata.dk/pipermail/net-z3950/2002-July/000136.html I managed to write a working program: #!/usr/bin/perl use Net::Z3950; #$conn = new Net::Z3950::Connection("LIBRARY.MIT.EDU", 9909, databaseName => "mit01") #$conn = new Net::Z3950::Connection("Z3950cat.bl.uk", 9909, databaseName => "BLAC") #$conn = new Net::Z3950::Connection("z3950.nls.uk", 7290, databaseName => "Endeavor") #$conn = new Net::Z3950::Connection("bobcat.nyu.edu", 210, databaseName => "GEAC") $conn = new Net::Z3950::Connection("z3950.loc.gov", 7090, databaseName => "Voyager") or die $!; $conn->option('preferredRecordSyntax', Net::Z3950::RecordSyntax::USMARC); $rs = $conn->search("\@attr 1=7 \"3764353651\"") or die $conn->errmsg(); #$rs->option(preferredRecordSyntax => "SUTRS"); #$rs->option(preferredRecordSyntax => "XML"); #$rs->option(elementSetName => "B"); my $n = $rs->size(); $rs->present(1, $n); print "found $n records:\n"; foreach $i (1..$n) { $rec = $rs->record($i) or die $rs->errmsg(); print $rec->render(); } $conn->close(); Then I looked in the processz3950queue and found: eval { $conn->option(preferredRecordSyntax => Net::Z3950::RecordSyntax::USMARC);} if ($globalsyntax eq "MARC21"); eval { $conn->option(preferredRecordSyntax => Net::Z3950::RecordSyntax::UNIMARC);} if ($globalsyntax eq "UNIMARC"); however there is no MARC21 choice in z3950servers.tmpl: <select name="syntax"> <option value="USMARC">USMARC</option> <option value="UNIMARC">UNIMARC</option> </select> I realized then that changing MARC21 to USMARC fixes the problem. Now I can succesfully use the library of congress in my searches. eval { $conn->option(preferredRecordSyntax => Net::Z3950::RecordSyntax::USMARC);} if ($globalsyntax eq "USMARC"); Hopefully this will come handy for someone else to running into the same problem.
