      • Database –is a collection of information that is organized and stored so it can be easily searched. Some examples of library databases are: Ocenet, EBSCO, HW Wilson, Lexjuris, ProQuest, and Adendi .
      • Home page – the first page you see when you start your web browser.
  • 6.
      • URL – each web page has a unique address called URL. All web pages URLs start with http://.
      • Domain name – tells you the official registered name of each site.
      • Domain extensions – are an extension of the URL.
        • .edu .org
        • .com .es
        • .gov .pr
        • .mil .net
  • 7. Searching information
      • When searching information it is important to learn about different types of searches:
      • Keyword search - by writing one or two words, you can locate web sites that offer the information you need.
    • Example: If you need to locate information about development in law about gay marriage. You can write: gay marriage law and will retrieve web sites that contain those words.
  • 8. To conduct a Keyword Search you can write the words that best identify your topic
  • 9. The search engine will retrieve Web pages that contain the words you used for the search
  • 10. Searching information
      • Boolean search – a search using the connectors and, or, not.
        • Example: if you want information about the legal issues of animal experimentation, then you can conduct a search using the following keywords:
          • Animal experimentation AND legal issues
        • Example: if you want information about the effects and causes of global warming, then you can conduct the following search:
          • global warming AND effects OR causes
  • 11. Not all the search engines recognize the Boolean Connectors. Yahoo recognize these connectors if you write them in capital letters
  • 12. The search engine retrieves the Web pages that include all the words you used to conduct the search
  • 13. Using the Boolean connector OR When writing effects OR causes, means that you want to retrieve Web pages that contain any of both words. This page only contains the word effects
  • 14. Searching information
      • When you search using a phrase, you should write it using “ “. Example:
        • “ effects of global warming” – this search retrieves web sites that contains exactly the phrase you wrote.
        • This search limits the results to only those web sites that contains this phrase.
  • 15. When searching for information about someone it is more effective to write the name in quotation marks, this way you retrieve the Web pages that contain the exact name
  • 16. Second part: Evaluating information
      • When you find information through the Internet, you should consider some aspects to determine if this information is correct.
      • You should evaluate each web site to determine if you can use this information.
      • To not evaluate a web site can make you use a wrong information.

      • If the purpose of the Web site is to sell or promote a product or service, it will offer the more convenient information for them, not for you.
