While this is certainly part of the answer we still don't know why the record length is off. The way I see it, there are two possible options: 1. Net::Z3950 is doing on-the-fly conversion of MARC-8 to Latin1 2. LC's Z39.50 server is emitting the records that way, and not updating the record length. I guess one way to test which one is true would be to query another Z39.50 server for the same record, and see if the same problem exists....in which case 1 is probably the case. //Ed
