1. Basic Research Tools

    BizNar scans all kinds of resources, including publications such as Advertising Age, government resources such as and the Bureau of Labor Statistics, news sources like Business Week and the Wall Street Journal, and social networks like LinkedIn and Wordpress.
    The US federal government, which collects all kinds of data, is a good source for student reports or business or general information purposes. They are often invisible because they are buried deep in massive websites and because the government is the unique source for important research and information.
  • Internet Archive

  • Pipl: People Search
    People Search identifies itself as the most comprehensive people search on the web and claims that its success is due to the fact that it taps Deep Web resources.
  • MedNar: Deep Web Medical Search
    MedNar's free search engine utilizes a federated search for medical resources. Results include an article link and source information. A topic breakdown for the search shows the number of articles available for each related topic.
  • Topsy: Real-Time Search for the Social Web
    Topsy can be searched by links, tweets, photos, videos, experts, and what it calls "trending." An "expert" search allows users to look for a subject and get results for people who have been posting on that topic, along with analytics on how often the search terms appear in an individual's postings.
  • Voice of the Shuttle(VoS): Website for Humanities Search
    Voice of the Shuttle(VoS) is a dynamic database of online resources on literature, the humanities, and cultural studies. It includes both primary and secondary resources and links to course materials, author websites, literature in English and other languages, and eBooks.

Welcome to the Deep Web Subject Guide!

What is the Deep Web?

  No matter how good you are at using web search engines (e.g., Google, Bing,       Yahoo, etc.), there are valuable resources on the web that commercial search   engines will not find for you. You can get to most of them if you know the URL,   but a general search engine search will probably not find them for you.

  These resources, often referred to as the Deep Web, the Hidden Web, or the       Invisible Web, contain a variety of content, including  databases of articles, data,   statistics, and government documents. The term invisible here refers to “invisible   to search engines.” There is nothing mysterious or mystical involved.
