Elaine, We had downloaded our authority files from our current system and used ./bulkauthimport.pl -file authorityfile.mrc to load them and then rebuild zebra with the -a switch.
I'm checking now about the 008 field. The ones I spot checked did have the a in the position 14 & 15, but, as I said, some did link, and those could have been the ones. I'll keep checking. Thanks for the help. On 4/19/2011 8:43 AM, Elaine Bradtke wrote: > We are using authorities, ours linked.
