Comparison 1 Introduction This article provides information on searching the Internet using Multi-search engines, rather than individual search engines, discusses the theory of how these things work, their advantages and disadvantages and finally presents the reader with a small tabular comparison of some major Multi-search engines. Why use a Multi-search engine? At the time of updating (February 2003) there are at least 150,000 different search engines (you can view the ones which I use most by visiting my search engine page) available which cover both general and specific subjects, or which search specific elements of the Internet such as Web pages or Usenet.While some of these are particularly effective and sophisticated none of them are entirely comprehensive. How do Multi-search engines work? From the explorations that I have undertaken, there appear to be 3 different approaches which are in operation at the moment:
OAIster [OCLC - Digital Collection Services] Access to OAIster A freely-accessible site for searching only OAIster records is available at Additionally, OAIster records are fully accessible through WorldCat.org, and will be included in WorldCat.org search results along with records from thousands of libraries worldwide. They will also continue to be available on the OCLC FirstSearch service to Base Package subscribers, providing another valuable access point for this rich database and a complement to other FirstSearch databases.

Pause Google: 8 Alternative Search Engines To Find What Google Can't On the information superhighway, we are at the helm of piloting a browser through the lanes and alleys of the web. To be a good driver, you need to be a master at the wheel. Would it be an apt metaphor to describe Google Search as that wheel which steers us from one lode of information to the next?

Instead, the self-described computational knowledge engine takes a completely different approach to letting users find and analyze information. Rather than scouring the Web and ranking everybody's pages in the order it thinks we'd find them useful, it uses its own data sets and computational power to return detailed reports and analysis about whatever topics users query it for. Tomorrow, the service will ramp things up a notch when its "pro" version launches. For $5 per month, Wolfram Alpha Pro will allow users to do way more with its data, as well as enable them to upload their own.
