I think the previous posting on the subject made the main points, which I would whole-heartedly endorse. It boils down to the fact that UK-MARC is a defunct standard which is no longer developed or maintained, which external databases no longer support (or will not support in the near future) and which library management systems will not support in the future either. At the moment, there is substantial expertise in how to convert data from UKMARC to MARC21 - that will slowly(?) disappear so you risk being left up a gum tree at some ill-defined point in the future. As to the experience, Leeds University migrated in 2002. The actual data migration was OK - though it can be a bit unforgiving if there are substantial unknown format errors in your data. Staff retraining went smoothly and everybody felt comfortable with MARC21 after about 3 months. MARC21 has strengths and weaknesses compared with UKMARC - they probably balance out overall, though the need to specify punctuation between subfields will drive you mad at first. But the bottom line is - you really don't have a choice. Either follow the standard or become progressively more out on a limb. Good luck!
