Does Google Go Deep Enough?

Does Google's Web Search Go Deep Enough Into Scholarly Archives?

Many scholarly archives on college and public Web sites don’t show up in Google because the search engine doesn’t index them — they’re in what many call the “deep Web,” below the level that most search engines look. A new study found that fewer than half — just 44 percent — of a sample group of deep-Web pages from scholarly archives showed up in Google searches. This is just another reason to use the databases provided by the Goodwin Library.
