drupalib A place for library drupallers to hang out

I just got my system set up to use this. The demo code was spraying out errors. I rewrote it to access the Library of Congress site and all the variables check out fine. I get records returned, but when I var_dump them they're all NULL. Can anyone help me configure my client settings and figure out where to get the info to set up on other servers.

I was using info from:
http://www.loc.gov/z3950/lcserver.html

I'm trying to get back XML to transform.

Thanks in advance.
