Challenges in library discovery

• Users start with ambiguous queries• More than half of queries are 1-3 words long

• Users need context• Why is something important?• What are my options?

• Users want ability to explore topics• 50,000+ topics searched over and over• The age of Wikipedia-driven inquiry

• Users don’t want to think• In an age of algorithms, why should they have to figure out

what’s available that matches their needs?

Discussion points

• What challenges to you see in your library related to discovery?

• How could we (the library community) provide a more consistent, data-driven view of what end-users need and want?

• Is it possible to create and adopt best practices to inform a consistent user experience?

• How can OCLC help drive improvement, regardless of which discovery product members choose to use?
