Yahoo has developed its Content Acquisition Program in order to index what's called "the deep Web" or "the invisible Web" -- the billions of documents contained in public databases which, for whatever reason, have been largely inaccessible to search engines. In its new endeavor Yahoo is aligned with the Library of Congress, the University of California at Los Angeles, National Public Radio, the University of Michigan and Project Gutenberg. Yahoo VP Tim Cadogan says, "One of the challenges is that the interaction between content providers and search engines is lacking. So we said, let's reach out to the public domains and nonprofits and try to get more of that content exposed." Cardogan says that about 99% of the company's search results draw on documents it has obtained freely from public Web sites, with the other 1% coming from Yahoo's paid inclusion program. The company maintains that there's an "iron wall" between commercial and free search results on Yahoo. This has been added to Deep Web Research Subject Tracer™ Information Blog.
