Information Literacy: Instruction for Your Classes: Invisible Web

Information Literacy: what it is, why it is important to you, and how to incorporate information literacy skills into your assignments.

Invisible Web

Google and other public search engines offer quick and freely available information. But how much of the web do they actually search? Estimates are around 30%. The rest of the Internet has been referred to as the dark, deep, or invisible web. "More than half of the deep Web content resides in topic-specific databases" (Bergman) such as the databases provided to you by the UK Libraries.
