American behavior about finding answers to questions

People ask per day an average of 4 questions that require an outside source

Americans have not yet found an ideal information resource; no participants said they would use the same resource time and again

More than 31 percent use Internet search engines to find answers; they often express frustration, however, because they estimate that half of their searches are unsuccessful.

Trends…The overall demand for quality metadata has dramatically increased Accelerating adoption of Internet technologyMore and more libraries worldwide, requiring authoritative electronic metadataEmergence of library portalsLooming library staffing shortagesIncreased competition from the private sector for skilled librariansFocus on enhancing access to the unique local collectionChanging measures: demonstrate effectiveness

Metadata…

Demystifying metadataIt’s information about information

Metadata is created by all librariansWhat do reference librarians use?What do bibliographic instruction librarians use?What do subject selectors use?

Metadata? Cataloging?

Why metadata?

Improves discovery and navigationEnables retrievalSupports administration

Why consider Dublin Core?You have a rich standard, but need a simpler one You want to reveal your data to other communities (via the web) using commonly understood semanticsYou want to provide unified access to databases with different underlying schemasYou need core description semantics and don’t feel compelled to invent them anew

CORC…

A familiar approach

Cooperation among libraries to . . . Enhance and expand accessProvide faster access to materialsMinimize duplication of effortIntegrate with local resourcesEnsure currency

Reasons for CORC Develop automated tools optimized for the description of web-based items Enhance access to the unique local collectionAssist libraries to participate in emerging digital global networkExtend and expand the WorldCat shared cooperative cataloging model to electronic resourcesExpand metadata formats within WorldCat to include additional resource communities
