I just tried the latest Net::Z3950 perl module and the rawdata() call now works. Woohoo! That means that I can now do Z3950 searches and download the raw marc data directly from Koha. Now I just wish I had two sweet clues how to format Z3950 queries. I know that @attr 1=4 "Linux" returns records with the title Linux. Anybody know what I have to use to search on ISBN or LCCN? Steve.
