Hi: I'm having trouble when I do z39.50 searching. Certain servers-- the New York Public Library [catnyp.nypl.org], or the Aurora Public Library [ odyssey.aurora.lib.co.us] for example-- will yield hits for results, but then only give me the message: 1: Permanent system error: Permanent system error: Bib-1 I don't know that this is a bug, really, but I'm trying to figure out exactly what is happening. Question one: what does this error actually mean? It seems to occur consistently for certain searches (ISBN-13 978-1-59722-733-9, for example gives me the error for both Aurora and the NYP consistently) while other searches can run through the same servers without a hitch. Is the "system" error my system, or theirs? Or is there some sort of compatibility issue? Two: beyond figuring out what's happening, I ideally would love to be able use z39.50 with these systems-- are other libraries able to accomplish this? Anyone else experienced this issue? There seem to be lots of servers that yield this error message-- I just listed these two as an example. (Incidentially, I'm using Koha 3.00.00.107) Max Crowe Library Director New Durham Public Library
