Why Google? The good: Intuitive interface; excellent image searches; best-of-class local searches, producing maps with satellite imagery; cached pages and related links; sponsored links clearly separated out into the right-hand column; desktop search tool; downloadable toolbar Source: CNET Reviews athttp://reviews.cnet.com/Google/4505-9239_7-31337412.html?tag=box

Google’s Limitations The not-so-good: Searching for audio files (includes files with .aiff, .au, .wav or .wave extensions)
Over 3000 file types! See list at: http://whatis.techtarget.com/fileFormatA/0,289933,sid9,00.html
Other Search Engines for Media • AlltheWebhttp://www.alltheweb.com • Search for news, audio, video* • Lycoshttp://www.lycos.com • Images, video
Search Engine Limitations Although large databases, provides access tosmall portion of what is available
The Invisible Web The Invisible Web is that portion of the Web that is not reached by standard search engines such as Google. It is estimated to be 2-500 times bigger than the visible web. It includes specialized searchable databases and search engines, archives of documents, documents in specialized formats, directories and locators, dictionaries, library catalogs, non-text files, and gated resources requiring a password or login Source: Beyond Google: Searching the Web More Effectively http://healthlinks.washington.edu/howto/beyondgoogle.html
Why Invisible? Real time content Formats Sites requiring login authorization Sites blocked by Robot Exclusion Protocols Sites requiring login authorization Interactive content Content generated dynamically as the result of a query Source: Beyond Google – The Invisible Web at http://www.lagcc.cuny.edu/library/invisibleweb/characteristics.htm
Robot Exclusion Protocols Use of blocking techniques by the webmaster or server Password protection • HTML blocking in the web page • A listing on the server of blocked pages
Content of Databases Information stored in tables (Access, Oracle, SQL Server, DB2) and accessible only by query: • Phone books, People finders • Patents, laws • Items for sale in a Web store or Web-based auctions • Digital exhibits • Multimedia and graphical files • Stock and bond prices
Deep Web Search Tools: Subject Directories Virtual Libraries Specialized Databases
Subject Directories Yahoo! Directory http://dir.yahoo.com/ Open Directory Project http://www.dmoz.org/ About.com http://www.about.com
Subject Directories Best used when you: have a broad topic want selected, evaluated, and annotated collections prefer quality over quantity aim to generate a list of sites/resources in a subject area
Avoid These Pitfalls: Browsing searchable directories Use the search box for a more efficient search Following links to sites recommended by heavy use or commercial interest Sites based on popularity ranking or on commercial fees paid Source:Search Strategies – Search with Peripheral Vision athttp://www.lib.berkeley.edu/TeachingLib/Guides/Internet/Strategies.html
Virtual Libraries INFOMINE — A virtual library of Internet resources relevant to university students and faculty. Built by librarians from the University of California, California State University, the University of Detroit-Mercy, and Wake Forest University. http://infomine.ucr.edu/
Virtual Libraries The WWW Virtual Libraryis the oldest catalogue of the Web, started by Tim Berners-Lee, the creator of HTML and of the Web itself, in 1991 at CERN in Geneva. Unlike commercial catalogues, it is run by a loose confederation of volunteers, who compile pages of key links for particular areas in which they are experthttp://vlib.org/
Free Searchable Databases Search tools for specialized subject areas Best used when you have a narrow topic E.g. law, health, business, science Good place to locate sources: Research Beyond Google (Online Education Database) http://oedb.org/library/college-basics/research-beyond-google
Specialized Databases • Law • Nolo Encyclopedia http://www.nolo.com • Medicine • PubMed (National Library of Medicine) http://www.ncbi.nlm.nih.gov/sites/entrez • Science • Scirus http://www.scirus.com/ • Intute http://www.intute.ac.uk/

Web 2.0 and New and Emerging Tools What is Web 2.0? refers to a perceived or proposed second generation of Web-based services—such as social networking sites, wikis, communication tools, and folksonomies—that emphasize online collaboration and sharing among users. Source: Wikipedia at http://en.wikipedia.org/w/index.php?title=Web_2.0&oldid=109754809
Web 2.0 Search Engines Rich Internet Application Search Interfaces (RIAs) Engines in this category offer a little something extra in terms of the interface
Kartoo www.kartoo.com Visual search engine Meta tool which presents results in map Analyses user’s search, questions the most relevant engines, selects the best sites and places them on a map

Wiki (n.) A collaborative Web site comprises the perpetual collective work of many authors. a wiki allows anyone to edit, delete or modify content that has been placed on the Web site using a browserinterface, including the work of previous authors term wiki refers to either the Web site or the software used to create the site. Wiki wiki means “quick” in Hawaiian Source: ISP webopedia.com athttp://isp.webopedia.com/TERM/W/wiki.html
Much Ado About Wikis Wiki bunfight (accuracy of online information) New Scientist 190.2545 (April 1, 2006): p7(1). “According to the survey, in 42 matching pairs of science entries on topics from Agent Orange to the West Nile virus, Wikipedia made 162 errors, which "comes close" to its competitor's 123.”
…Wikis Journal Gives Wikipedia High Marks for Accuracy, but Not for Readability.(Nature )(Brief article). Dan Carnevale. The Chronicle of Higher Education 52.19 (Jan 13, 2006) “Other than errors, Nature's experts found that the Wikipedia entries were often poorly worded and confusing. While the information was generally reliable, the Nature article says, entries often lacked the nuance that a subject-matter expert could provide, as well as good editing.”
Use with caution! Articles carry warning: “As with any community-built reference, there is a possibility for error in Wikipedia's content — please check your facts against multiple sources and read our disclaimers for more information.”
Directories of Wikis • Wikia.com www.wikia.com A directory of wikis that is searchable and browsable by categories, language, and more. • WikinsideA Google CSE that searches text within about 3,000 wikis • WikiIndex.org wikiindex.org A wiki that is a directory of wikis
