1. How Authorities Processing Improves Results with Encore and Other Catalog Search Overlay Products Joan Chapa

2. Introduction Current online catalogs reflect a legacy of card catalogs. Library technology lags behind the popular search engines commonly used today Many libraries frustrated that their catalogs (a major investment) are not being used to full potential. “Known-item” searches are what these catalog searches do best

3. Products to Enhance Discoverability New products developed to harvest data from library OPAC and other sources Identified as: catalog overlay, discovery tools, library resource portal, discovery layer, etc. Usually platform independent –Encore (III) –Primo (ExLibris) –AquaBrowser and Summon (Serials Solutions) –VuFind (open source, originated at Villanova University)

4. No Authorities? Lipstick on a Pig Implementation of these discovery tools without authority control has been described as putting lipstick on a pig.

5. Why Is Authority Control Needed? Encore creates tag cloud terms from LCSH, so current terms and “see froms” are needed Facets display a number of areas, including authors One facet extracts data from form subdivision in $v. If data is still in $x, information may not be properly faceted. Correction of $x to $v is done during authority control.

6. Keyword Search Yields Too Much Keyword searching often yields too many hits “Related Searches” use authority records to allow a more nuanced search Search in MSU catalog: Global warming “Related Searches” Plants, Effect of global warming on

8. Preferred Terms Authority control provides the user with the term that is currently used Also adds current term to tag cloud Search in UC-Boulder catalog: Orientals “Related searches” Asians

10. Pseudonyms Keyword searching also does not allow for pseudonyms Authority record points to other works by the same author under a different name, narrowing the search Search in HPL catalog: Julie Andrews “Related searches” points to her books for children under name Julie Edwards

12. Uniform Titles Uniform titles further enhance discovery Critical for music searches, scores & sound recordings. Popular form of title is in uniform title. Search on popular name without authority cross reference in place. Work is lost! Search in UC-Boulder catalog: Cradle song “Related searches” lists uniform title of Cradle song for various composers
