    1. How to Search the Web An ACC Library Tutorial
    2. How to Search the Web This tutorial offers simple approaches to Web searching and evaluation. Take 10 minutes now to save hours of searching later!
    3. First: some quick Web basics: The World Wide Web is an interconnected network of computers around the world. No group controls the quality of Web sites. Checking Web information is your job!
    4. Much information is on the Web… Valuable, credible information:  research, statistics, health news, financial data from governments and non-profit groups; Hobby and personal information, by  individuals; Commercial advertising from companies;  Inaccurate, offensive  information, rantings, opinions presented as facts, child pornography, stolen music, etc.
    5. So…is everything on the Web?? NO! No one publishing medium contains all information in the world: not books, TV, radio, films , or the Web! By far, most information in the world is NOT on the Web.
    6. When to use the Web in research: It’s often best to use Web sites after using books and articles, which are usually fact-checked by experts. Learn about your subject in reliably credible sources first, so you can evaluate Web sites better!
    7. Using computers at ACC: Computers with Web access are located: near the Reference Desk in the ACC – Library in Scoville Learning Center, the Student Computing lab on the – lower level of Scoville, the Student Center and other locations – around campus. Using these computers indicates your consent to ACC’s Computer Use Policy.
    8. Wi-Fi Access ACC students, faculty and staff can  use their usernames and passwords to log in to the wireless system in the Scoville building. Stop by the reference desk first for the  Wireless Access Password sheet.
    9. Free vs. subscription Web sites: Just like with network and cable TV, there  are free and paid or subscription Web sites. You generally get what you pay for! This tutorial discusses ways to search for  the best free Web sites. Students have free access to subscription  Web sites (such as article databases) on ACC Library’s Web page.
    10. Let’s go through these questions to evaluate Web pages: 1) Who created the page? 2) How current is it? 3) Does it show a bias or limited point of view? 4) Is it accurate?
    11. 1) Who created the Web page? Who is the author or  producer? Are credentials or contact  information given? If published by an  organization, is any background given? Is it the group’s official site? 
    12. Check the address endings! The last part of a Web address may tell you who  created the site: .com (for-profit company; about 50% of addresses), .gov (U.S. federal government), .edu (college or university), .org (non-profit organization), .net (network) and .mil (military). Two-letter country (.us) or state (.ny) addresses are also used. New Web address endings are being added:  …and others. .biz .museum .info .pro
    13. 2) How current is the Web site? When was the  information produced? When was it last  updated? Does the currency  matter for your subject? Are the links up-to-  date, or do they lead to “dead ends”?
    14. 3) Does the Web site have a bias? Does the site offer facts  or opinions? Are political, cultural or  other biases evident? Does it present all  viewpoints, or selected ones? Is the author trying to  sell a product or have other vested interests?
    15. 4) What is the Web site’s content? What is the site’s purpose?  Is it accurate? Does it  correspond to research in more reliably credible sources? Who is the intended  audience? Is it clearly organized and  designed well?
    16. Four ways to search the Web: Use these approaches in this order to save time and get the best search results: Recommended Web sites  Subject directory  Search engine  Meta-search engine  Let’s go through each….
    17. 1) Recommended Web site: This technique is learned with experience. Check textbooks, ACC Library research guides and with your instructor for ideas. We’ll get you started with a few favorites….they might become your favorites too!
    18. Some Web addresses recommended by ACC librarians: FedStats: http://www.fedstats.gov Federal and state statistics NewsVoyager : http://newsvoyager.com Links to many U.S. newspapers RefDesk: http://refdesk.com News, weather, reference Web sites
    19. 2) Subject Directory: Subject directories are Web sites offering:  a small, organized collection of high-quality Web sites.  sites chosen by people, not software. Use them to find a few good, credible Web sites.
    20. Examples of subject directories: Commercial subject directories are fine for movie reviews, recipes, and other non-college research. They rarely evaluate sites for quality. Yahoo! Google Directory For research papers, use the ones on the next page…
    21. Non-profit subject directories: For college-level research: Librarians’ Internet Index: http://lii.org Thousands of sites chosen by Library of California. Internet Public Library http://ipl.org From the University of Michigan. (Save these as favorites on your computer!)
    22. Try out a subject directory… Test a subject in Librarians’ Internet Index: http://lii.org Click on the categories for Health, Money, Statistics, Education, etc. Find good Web sites in seconds!
    23. 3) Search engines: Search engines search millions or billions of Web  sites by subject, using software. They’re useful for very specific subject searches,  or if you want many, many results. Search engines Web sites are  usually not organized by subject, nor quality-oriented.
    24. Google remains the most popular search engine… It’s a “second generation” search engine, using link popularity and other criteria to find useful sites. It searches several billion sites. But if you’re going to Google…
    25. Use Google’s “Advanced Search”! Click on Advanced Search to right of 1) Google’s search box. Use these options if helpful: “this exact wording or phrase”  “search within a site or domain” limit: (search  for gov or edu or org endings) “any of these unwanted words” to omit sites  with “com” endings.
    26. There are other search engines! No search engine covers all the Web. More than a thousand search engines exist. Compare a Google search with these: Ask.com AllTheWeb For 200+ more search engines, see Search Engines & Web Directories
    27. 4) Meta-search engines: These are search engines that search other search engines. They cull the top results from – several search engines. It’s a broad, shallow way to – search. Use this method last, to find – “needle in a haystack” facts.
    28. Examples of meta-search engines: MetaCrawler SurfWax Ixquick See this Meta-Search Engines page for 90  more.
    29. This tutorial was created for Adirondack Community College students by ACC instruction librarian Joyce Miller.
