I’m not sure sure if there’s a name for these homegrown federated search services that let a library offer a single search box that serves up search results bento-box style from the catalog, a discovery tool, the library website, etc. The libraries at the University of Michigan and North Carolina State University have had such search tools for a while; now it looks like Columbia University is testing one out, too: CLIO Beta.
Announcing CLIO Beta (video intro)
For the “Articles” search piece, it looks like Columbia is using the API from their Summon subscription. For the “Catalog” search and the “Academic Commons” (the institutional repository) search pieces, they seem to be using Blacklight, an open source discovery layer developed by the University of Virginia.
