Hi Elaine, Yes as long as your unique number is in the 001 you can set up a new match rule referring to "Control-number" and match on that. I use that quite a lot. I think I posted about it about a year ago. The Community documentation should be enough to get you going but do come back if you need more detail. Cheers.

Ours is a rather quirky collection, I know. But an awful lot of it doesn't have an ISBN or ISSN (1364 biblios in a collection of 1664 fall into this category). I am working on a project to batch change all the biblios in a particular collection. Selecting them, downloading them, and editing the MARC records was easy. Now I would like to upload them and overwrite the old records. This only seems possible for the 300 biblios with an ISBN. We have unique internal control numbers (001). Is there any way I can match the records with this field instead? If not, what are my other options?
