Good morning, I asked this question last week, but I don't think I was clear on what I was trying to do. If I want to upload one branches marc records by bulkimport, can I do that and not erase the rest of the Marc records that belong to other branches. I finally got to the point to upload the MARC and how I could delete the old records, my fear at that point was that I would delete the other 15 libraries records, this would not make me popular. While we are spread far apart in my school district (15 schools over 65,000 square miles with only airport travel between villages) I have invited everyone to come to a training in October. I think they would remember me taking down their whole system.
