Searching the invisible web (deep web, hidden web): WebLens sear Custom Search Locate deepweb resources by adding the word database to a regular search engine query. The terms invisible web, hidden web, and deep web all refer to the same thing: a massive storehouse of online data that regular search engines don't capture.

Nonprofit Common Crawl Offers a Database of the Entire Web, For Free, and Could Open Up Google to New Competition Google famously started out as little more than a more efficient algorithm for ranking Web pages.

A nonprofit called Common Crawl is now using its own Web crawler and making a giant copy of the Web that it makes accessible to anyone. The organization offers up over five billion Web pages, available for free so that researchers and entrepreneurs can try things otherwise possible only for those with access to resources on the scale of Google’s.
