batch query
I am a newbie when it comes to querying the Z39.50 server using perl module. I would appreciate some help. I am reading in around 900 or so ISSNs from a text file and outputting the title and subject in a xml file. For some reason, the loc server times out after returning 70 or so records ( '@attr 1=8 @attr 3=1 ' . $issn) and I get this error: Can't call method "option" on an undefined value at write.pl line 62, line 902. I am using MARC::Field to get the 650 record. Also for the same ISSNs and query string, I am getting blank subjects from the oclc server. However, that server does not time out. Any idea? --sharif -- Sharif Islam Research Programmer Library Systems Office University of Illinois Urbana-Champaign http://www.library.uiuc.edu phone: (217) 244-4688
