websites Password required to join the party
authentication/authorization More services, more resources
Challenges Speed Inconsistent implementation of standards Aggregating/presenting results from
disparate resource types New - cultural heritage institution
resources Different standards, software, & record
structures Maintaining interoperability Subject headings, thesauri, terminology Integrating multiple software packages Linkages and bread trails
Metasearch – the future
Think beyond current resource targets Seamless integration of searching and
services Integration with digital government New interface viewpoints
GIS Temporal spatial access Tempo-dynamic research
Multiple user role viewpoints
Teen’s view Single search box, but— multiple windows with
multiple simultaneous activities Immediate gratification – full text, complete
object 24/7 online chat with librarian for assistance Resource targets
Websites Video clips Audio clips Animation Games Online classes Last resort – books, magazine articles
Genealogist’s view Single search box Date limit Geographic limit – place name and lat/long codes Personal name as subject and/or author Resource targets
Newspaper full text Magazine article full text Manuscripts, diaries Public records – birth, death, property Cemetery records Digital objects – photos, oral histories, video clips
Temporal spatial view Layers of photographs of same physical location over time
K12 Educators View Single search box Returns selected “best” results – not
comprehensive Grade level and reading level limits Linked to state education standards Resource targets
Websites Full text books, articles Primary source material Digital objects – photos, audio, video Educational objects Lesson plans
Information Gathering Comments submitted via website Informal discussions Review of other public portals Focus groups with target audiences
