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? -- Elaine Bradtke Data Wrangler VWML English Folk Dance and Song Society | http://www.efdss.org Cecil Sharp House, 2 Regent's Park Road, London NW1 7AY Tel +44 (0) 20 7485 2206 (This number is for the English Folk Dance and Song Society in London, England.
