Hello I am a new user of KOHA who is trying to set up a research library for a new museum opening in Phoenix, Arizona, USA. My problems are multiple: 1. I am untrained in MARC since MARC was not around when I graduated from library school although I have been valiantly reading MARC how-tos. 2. I do not have KOHA presently available to me. 3. I am encountering many questions about both MARC and KOHA as I work and so I am hoping that you kind people can give me answers. One of my questions is this: I have encountered a few Library of Congress records that contain typos. How would I correct those records for my own library? PF Corman
