How do we know when there are errors in the catalog? Sierra’s Headings Reports tell us – among other things – when there are duplicate records in the system, when an author heading may be out of date, or when subject headings are no longer being used in the catalog. But how are Headings Reports generated, what are they really telling us, how do we fix the problems, and most importantly, how do we know when we can take no action? The MOBIUS Office presents this informative look at Sierra’s Headings Reports. Topics will include indexing and headings normalization, an overview of authority processing, and a hands-on look at the Sierra Reports, including how they are generated and what to do with them.
