what is federated search?

  • Searches multiple databases at once and presents results
  • problems with relevancy in result sets

usage overall is going up

marketplace is in flux > consolidation
It’s a mess!

federated search as one module of a larger effort to integrate all content into a single discovery tool
now work with next-gen OPACs:

  • worldcat local
  • primo
  • aquabrowser
  • encore

open source strategies

  • Library Find (Oregon state)
  • dbWiz (Simon Fraser University)

encore from III – has phrase tag cloud, not just word tag cloud; connects to indexing for records
Primo – university of iowa
