Following up on some listserv discussion in mid-February, I'm trying to create some new record matching rules. I'm having trouble figuring out what to use for the "index" field. The delivered ISBN & ISSN match rules both use isbn as the index, but I've seen one other example where ISSN uses issn as the index. I also want to create rules for bib # (999|a) and LCCN. The only place I've found any index names anywhere is in the NoZebraIndexes syspref. If I use those names, it looks like 999 would be biblionumber (except that's spec'd as 999|c) and LCCN would be lccn. But we're using Zebra so those index names may be irrelevant anyway. Does the index name matter in the matching rule if we're using Zebra? Thanks. Jane Wagner Library Systems Analyst PTFS Inc.
