Academic and General Subject
Directories -Subject and academic
directories are often a good starting point to finding quality
information-specific websites. The web-based subject directories
listed below generally provide an organized list of websites grouped
according to specific subject and can often be searched by keyword.
When using keywords, the use of subject-specific terms may yield the best
results. It is important to remember that websites are not
evaluated for content and validity of information, but many are rated based
on the popularity of use. Because it is not possible for every
search engine to provide access to all websites and online information
(see section on the Invisible Web), it is necessary for you to be
able to properly evaluate websites to determine the most accurate
information.

most authoritative sites on the Web. Our ExpertRank algorithm
goes beyond mere link popularity (which ranks pages based on the sheer
volume of links pointing to a particular page) to determine
popularity among pages considered to be experts on the topic of your search. This is known as subject-specific popularity. Identifying topics
(also known as "clusters"), the experts on those topics, and the
popularity of millions of pages amongst those experts -- at the exact moment
your search query is conducted -- requires many additional calculations
that other search engines do not perform. The result is world-class
relevance that often offers a unique editorial flavor compared to other
search engines.”
