1. Search Engines


N
ame: Google
URL: www.google.com
Size: Not released, estimated 20 B+  
Special Features: By far the most popular search engine Google uses a complicated mathematical analysis, calculated on more than a billion hyperlinks on the web, to return high-quality search results so you don't have to sift through junk. This analysis allows Google to estimate the quality, or importance, of every web page it returns. Makes heavy use of link popularity as a primary way to rank web sites. Also provides results for AOL, and Netscape. "Sponsored Links" are generated by allowing advertisers to bid for placement in this area based on relevant keywords. 


Name:
Teoma/Ask.com
URL:
www.ask.com
Size:
2 billion+
Special Features:
Instead of ranking results based upon the sites with the most links leading to them, Teoma analyzes the Web as it is organically organized—in naturally-occurring communities that are about or related to the same subject—to determine which sites are most relevant. Teoma is the only search technology that can locate communities on the Web within their specific subject areas, as they actually exist. And this allows us to finely tune our search process, providing more precise results. Provides results for Ask, Ask-Jeeves,

Academic/Scholarly Search Engines
Now with Buley Holdings Information!!

Name:Google Scholar
URL: scholar.google.com
Special Features: Google Scholar enables you to search specifically for scholarly literature, including peer-reviewed papers, theses, books, preprints, abstracts and technical reports from all broad areas of research. Use Google Scholar to find articles from a wide variety of academic publishers, professional societies, preprint repositories and universities, as well as scholarly articles available across the web. Just as with Google Web Search, Google Scholar orders your search results by how relevant they are to your query, so the most useful references should appear at the top of the page. This relevance ranking takes into account the full text of each article as well as the article's author, the publication in which the article appeared and how often it has been cited in scholarly literature. By going to the preferences you can set up Google scholar to show our links off campus.


Name:
Windows Live Search Academics
URL: academic.live.com
Special Features: Although available to anyone, Windows Live Academic Search is designed to help students, researchers and university faculty conduct research using academic and scholarly journals. Although search results are free, the library must have a subscription to a journal or pay on a per-article basis to access the full text. To see if we have the article and determine how to find it click on the link "Full-text @ Buley Library". Unlike Google Scholar , which crawls the web for academic content, Windows Live Academic Search works closely with publishers and uses structured feeds to build its index. As such, all content accessed through the service comes directly from a trusted source—namely, the publisher of a scholarly journal. At present it is only possible to use this product on campus and get the library links. Off campusyou will see no library link. It is expected to be usable off campus in the next release.

2. Specialized Search Engines
Specialized search engines are designed to deal with some of the limitations of the regular search engines. They can often make searching much more efficient.
