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 technology
More and more libraries worldwide, requiring
authoritative electronic metadata
Emergence of library portals
Looming library staffing shortages
Increased competition from the private sector
for skilled librarians
Focus on enhancing access to the unique local
collection
Changing measures: demonstrate effectiveness
Metadata…
Metadata? Cataloging?
Demystifying metadata
It’s information about information
Metadata is created by all librarians
What do reference librarians use?
What do bibliographic instruction librarians use?
What do subject selectors use?
Why metadata?
Improves discovery and navigation
Enables retrieval
Supports 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 semantics
You want to provide unified access to
databases with different underlying
schemas
You need core description semantics and
don’t feel compelled to invent them anew
CORC…
A familiar approach
Cooperation among libraries to . . .
Enhance and expand access
Provide faster access to materials
Minimize duplication of effort
Integrate with local resources
Ensure currency
Reasons for CORC
Develop automated tools optimized for the
description of web-based items
Enhance access to the unique local collection
Assist libraries to participate in emerging digital
global network
Extend and expand the WorldCat shared
cooperative cataloging model to electronic
resources
Expand metadata formats within WorldCat to
include additional resource communities
