1. User interface choices & decisions
2. User feedback & behaviour
UI Choices: Basic Search Screen
• just a search box & go?
• include choice of search indexes? (fielded searching)
• include alpha as well as keyword indexes?
• include limiting at time of search?
Search ‘n’ Go: UWO (Encore)
Search ‘n’ Go: Queens N.Y. (Aquabrowser)
Search ‘n’ Go & Limit by Collection: Vanderbilt (Primo)
Choice of Keyword Indexes: U of T (Endeca)
Choice of Keyword Indexes & Databases:
Villanova U. (VuFind)
Choice of Keyword & Alpha Indexes: Florida State U. (Endeca)
Choice of Keyword & Alpha Indexes: McMaster (Endeca)
Choice of Keyword/Phrase Indexes & Limit by Format, Location:
Waterloo (Primo)
UI Choices & Decisions
• Search, search within results, start over – Oh my!
Search Within Results; Search button; Start Over link
New Search button; Search Within Results button
UI Choices: defaults
• facets: open, closed or a mix?
• after a closed facet has been opened, keep it open?
• after a search, keep the previously selected index chosen, or return to the default?
UI Choices: facets
• which? hierarchical or flat?
• what to call them?
• display order
• order of values within facets: alpha or most hits at the top?
• all “and” or some “or”?
UI Choices & Decisions
• Search logic– match on any 1, 2, 3 terms, all terms?
• Display– how to display the full bib & item details
• Alpha indexes– how to display?
1. User interface decisions2. User feedback & behaviour
McMaster’s Initial Implementation
• Spring 2007
• usability testing
• feedback via “Tell us what you think” button in catalogue
• most feedback within first 3-4 months
Some interesting resultsfrom usability tests...
• only 1 of 5 subjects used the dimensions (oh no!)
• some subjects relied on type-ahead to complete all queries
User Feedback: Negative
Suggestions/Problems/Questions
User Feedback: Positive

The hope, the promise
• One search box to provide fast and convenient access to all of our resources, regardless of format– Enable access to our digitized cultural memory– Address disjointed library experience– Attempt to remain relevant to web savvy users– Provide Google-like relevance and react to challenges
on the commercial internet
Considerations, challenges
• Existing OPAC features • Becoming an aggregator
– Can we ever get metadata/access to everything?– Native interfaces– A lot of data
• Controlled vocabulary cross walks • Local modifications and needs• Partners/Community and Collaboration
