What’s Federated Searching? (1)
• Federated Search:
“A search for information using software designed to query multiple networked information resources via single interface.” - Online Dictionary for Library and Information Science http://lu.com/odlis/odlis_f.cfm

What’s Federated Searching? (2)• Search scope: expanded
– OPACs (local, remote), databases (abstracting, full text), digital repositories, WWW (including “deep Web”)
• Software: federated search engine– Standardized protocol (Z39.50, SRW/SRU, MXG)
• Results presentation: uniform interface– Ranking: software feature that weights records by the
degree to which they meet the query’s requirements– Deduping: removal of all but 1 occurrence of a record

“[Database searchers] don’t go to see if another database might have more and/or better results…. Most give up and angrily leave…. They’ll go to Google….” – Dr. Péter Jácso
