Eric, How is this 'new type' of index any different from an index of OAI-PMH harvested material?

Sounds like good PR to me, rather than a revolution ;) Rob On Tue, 21 Apr 2009, Eric Lease Morgan wrote: > On Apr 21, 2009, at 10:40 AM, Mike Taylor wrote: >> I, and most of the people I've worked with, have been using the terms >> "metasearch", "federated search", "broadcast search" and "distributed >> search" synonymously for years.
