17About discovery
- From inventory to discovery (and back again)
- Keyword searching versus index browsing
- Relevance ranking precision, recall and first
page principle
18Open Source or Vendor
- open source
- e.g. VuFind, eXtensible Catalog, SOPAC
- ILS vendors
- e.g. Primo (Ex Libris), Encore (III)
- other vendors
- e.g. Endeca, BiblioCommons
- AquaBrowser, OCLC, Serials Solutions
19Local or Hosted, Customize or Not
- Local
- hardware/software infrastructure
- some local configuration possible
- Hosted
- minimal local hardware/software
- ideally a service to manage user generated
content - Either data matters
20Web 2.0
- Why?
- interaction with collections
- reliance on peer and expert opinion
- social search
- What? Where? How?
- user generated content
- academic concerns, placement, web scale
- usage logs, recommender systems
21Summary some factors to consider
- User experience
- degree of integration
- search intelligence
- extensibility
- Local (or consortial) capacity
- time and money

59The 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
60Considerations, 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
