Abstract: Search engines are about excitement, optimism, hope and enrichment. Search engines are also about despair and disappointment. A researcher while using search engines for resource discovery might have experienced one or the other sentiments. One may say that user satisfaction depends much upon the search strategies deployed by the user. But at the same time its also depends upon the quality of search engine used for information retrieval. Today, there are many search engines used for resource discovery. They display the results of the searches made in readily-comprehensible manner with lots of customization possibilities including refining and sorting. This paper is an attempt to analyze qualitatively and quantitatively the three most used and popular search engines for academic resource discovery: Google Scholar, Scirus and Windows Live Academic.

Abstract: Invisible Web which is also known as ‘Deep Web’ or ‘Hidden Web’ refer to information content that is ‘invisible’ to conventional search engines. Public information on the invisible web is currently around 500 times larger than the commonly defined World Wide Web. Nearly 550 billion individual documents are available in the invisible web while the surface web has around only one billion documents. It has been estimated that around 2,00,000 invisible web sites exist on the Information Superhighway at present and is the largest growing category of new information on the Internet. The total quality content of the invisible web is also greater than that of the surface web and highly relevant to every information need, market and domain. But, a larger portion of the invisible web is missing from search engines’ results pages. In this context, this paper attempts to characterize the deep web’s content and relevance to information seekers and profile special tools available to mine the invisible web.
