Lorcan Dempsey's weblog
Another good (and brief) overview from Lorcan Dempsey on the difference between the library world, the google world, and the meta meaning of meta searching.
"So, metasearch is one response to fragmentation, albeit one with limited effectiveness. Another approach is to consolidate data resources into larger reservoirs. This has the advantage of reducing the burden of integration, and enhancing the ability to create value-added services. But how and at what level could this be done? What are the sensible and possible consolidations in between the universal Google and the current debilitating fragmentation?"
