Invisible Web Gets Deeper By Danny Sullivan From The Search Engine Report Aug. 2, 2000 I've written before about the "invisible web," information that search engines cannot or refuse to index because it is locked up within databases. Now a new survey has made an attempt to measure how much information exists outside of the search engines' reach. The company behind the survey is also offering up a solution for those who want tap into this "hidden" material. The study, conducted by search company BrightPlanet, estimates that the inaccessible part of the web is about 500 times larger than what search engines already provide access to. To put that another way, Google currently claims to have indexed or know about 1 billion web pages, making it the largest crawler-based search engine, based on reported numbers. That sounds terrible, but as I've commented numerous times before, the size of a search engine does not necessarily equate to its relevancy or usefulness. Now let me make one final distinction.

Invisible Web What is the "Invisible Web", a.k.a. the "Deep Web"? The "visible web" is what you can find using general web search engines. It's also what you see in almost all subject directories. The first version of this web page was written in 2000, when this topic was new and baffling to many web searchers. These types of pages used to be invisible but can now be found in most search engine results: Pages in non-HTML formats (pdf, Word, Excel, PowerPoint), now converted into HTML.

How to Find the Invisible Web Simply think "databases" and keep your eyes open. Use Google and other search engines to locate searchable databases by searching a subject term and the word "database".

The Ultimate Guide to the Invisible Web Search engines are, in a sense, the heartbeat of the internet; “Googling” has become a part of everyday speech and is even recognized by Merriam-Webster as a grammatically correct verb. It’s a common misconception, however, that Googling a search term will reveal every site out there that addresses your search. Typical search engines like Google, Yahoo, or Bing actually access only a tiny fraction — estimated at 0.03% — of the internet. The sites that traditional searches yield are part of what’s known as the Surface Web, which is comprised of indexed pages that a search engine’s web crawlers are programmed to retrieve. "As much as 90 percent of the internet is only accessible through deb web websites." So where’s the rest? So what is the Deep Web, exactly? Search Engines and the Surface Web Understanding how surface pages are indexed by search engines can help you understand what the Deep Web is all about.

National Atlas home page The National Map is now offering a collection of small-scale datasets that can be downloaded for free. Although the 1997-2014 Edition of the National Atlas of the United States was retired in September 2014, The National Map recognizes the importance of continuing to make a collection of the small-scale datasets, originally developed for the National Atlas, available to users. Small-scale maps have an advantage over large-scale maps when there is a need to show a large area in a single view. This makes small-scale maps an ideal solution for scientists, decision-makers, and planners needing to provide a geographical context for the research projects. The National Map collection of 197 small-scale datasets can be downloaded at small-scale data download page . Even though the 1997-2014 Edition of the National Atlas has retired, nationalmap.gov will continue to offer the Set of Dynamic Topographic Maps Illustrating Physical Features.
Database search engine There are several categories of search engine software: Web search or full-text search (example: Lucene), database or structured data search (example: Dieselpoint), and mixed or enterprise search (example: Google Search Appliance). The largest web search engines such as Google and Yahoo! utilize tens or hundreds of thousands of computers to process billions of web pages and return results for thousands of searches per second. Searching for text-based content in databases or other structured data formats (XML, CSV, etc.) presents some special challenges and opportunities which a number of specialized search engines resolve. Database search engines were initially (and still usually are) included with major database software products. In more advanced Database search systems relational databases are indexed by compounding multiple tables into a single table containing only the fields that need to be queried (or displayed in search results).
