Hi Evelyn, We use the following rule with success: Search Index: utility Source: 1100 Tag: 001 Subfields: a Offset: 0 Length: 0 Normalization rule: ISBN You can assign whatever number (over 1,000 I think) in the "Source" box. This is part of a multi match point rule that we have set up and we assign different source numbers to each match point with the idea that the match score would tell us which point(s) the match was made on. I hope this helps you. Nora ________________________ Nora Blake MassCat Manager Massachusetts Library System P.O.
