Moving Beyond Metasearching: Are Wrappers the Next Big Thing
"A student searches a ProQuest database and has found a pertinent article. That article would contain a variety of "anchors" or icons links related to the author or keywords. Clicking on the icons would lead to content in the book catalog or in other databases; a video in a digital repository; notes a local professor has added to the article; or the author's web page. It might even link to services like MapQuest or an "Ask the Expert" page.
It's simple: users don't have to think about what they're doing. And unlike federated searching Bieber claims the native power of each interface will still be maintained."
