The Internet is a series of networks that are interconnected all over the world. The Internet allows users to have almost unlimited access to information stored on the networks. Dr. Berners-Lee, a physicist, created the Internet in the 1980s by writing a small computer program that allowed pages to be linked together using key words. The Internet was mostly text-based until 1992, when a computer program called the NCSA Mosaic (National Center for Supercomputing Applications at the University of Illinois) was created. This program was the first Web browser. The development of Web browsers greatly eased the ability of the user to navigate through all the pages stored on the Web. Very soon, the appearance of the Web was altered as well. More appealing visuals were added, and sound was also implemented. This change made the Web more user-friendly and more appealing to the general public.

Before you begin a search, you should identify your specific topic. To make searching easier, narrow your subject to a key word or a group of key words. These are your search terms, and they should be as specific as possible. For example, if you are looking for the latest concert dates for your favorite musical group, you might use the bands name as a key word. However, if you were to enter the name of the group in the query box of the search engine, you might be presented with thousands of links to information about the group that is unrelated to your needs. You might locate such information as band member biographies, the groups history, fan reviews of concerts, and hundreds of sites with related names containing information that is irrelevant to your search. Because you used such a broad key word, you might need to navigate through all that information before you find a link or subheading for concert dates. In contrast, if you were to type in Duplex Arena and [band name] you would have a better chance of locating pages that contain this information.

If you have a large group of key words and still dont know which ones to use, write out a list of all the words you are considering. Once you have completed the list, scrutinize it. Then, delete the words that are least important to your search, and highlight those that are most important.
These key search connectors can help you fine-tune your search:

AND: narrows a search by retrieving documents that include both terms.
For example: baseball AND playoffs
OR: broadens a search by retrieving documents including any of the terms.
For example: playoffs OR championships
NOT: narrows a search by excluding documents containing certain words.
For example: baseball NOT history of

Tips for an Effective Search
|
|
|
- Keep in mind that search engines can be case-sensitive. If your first attempt at searching fails, check your search terms for misspellings and try again.
- If you are entering a group of key words, present them in order, from the most important to the least important key word.
- Avoid opening the link to every single page in your results list. Search engines present pages in descending order of relevancy. The most useful pages will be located at the top of the list. However, read the description of each link before you open the page.
- When you use some search engines, you can find helpful tips for specializing your search. Take the opportunity to learn more about effective searching.

How you search should be tailored to what you are hoping to find. If you are looking for data and facts, use reference sites before you jump onto a simple search engine. For example, you can find reference sites to provide definitions of words, statistics about almost any subject, biographies, maps, and concise information on many topics. Some useful on-line reference sites:
|
|
|
|
On-line libraries
On-line periodicals
Almanacs
Encyclopedias
You can find these sources using subject searches.

As you prepare to go on-line, consider your subject and the best way to find information to suit your needs. If you are looking for general information on a topic and you want your search results to be extensive, consider the subject search indexes on most search engines. These indexes, in the form of category and subject lists, often appear on the first page of a search engine. When you click on a specific highlighted word, you will be presented with a new screen containing subcategories of the topic you chose. In the screen shots below, the category Sports & Recreation provided a second index for users to focus a search even further.

Just as you would evaluate the quality, bias, and validity of any other research material you locate, check the source of information you find on-line. Compare these two sites containing information on the poet and writer Langston Hughes:
Site A is a personal Web site constructed by a college student. It contains no bibliographic information or links to sites that he used. Included on the site are several poems by Langston Hughes and a student essay about the poets use of symbolism. It has not been updated in more than six months.
Site B is a Web site constructed and maintained by the English Department of a major university. Information on Hughes is presented in a scholarly format, with a bibliography and credits for the writer. The site includes links to other sites and indicates new features that are added weekly.
For your own research, consider the information you find on Site B to be more reliable and accurate than that on Site A. Because it is maintained by experts in their field who are held accountable for their work, the university site will be a better research tool than the student-generated one.

Tips for Evaluating Internet Sources
|
|
|
|
1. |
Consider who constructed and who now maintains the Web page. Determine whether this author is a reputable source. Often, the URL endings indicate a source.
|
|
|
|
- Sites ending in .edu are maintained by educational institutions.
- Sites ending in .gov are maintained by government agencies (federal, state, or local).
- Sites ending in .org are normally maintained by nonprofit organizations and agencies.
- Sites with a .com ending are commercially or personally maintained

Skim the official and trademarked Web pages first. It is safe to assume that the information you draw from Web pages of reputable institutions, on-line encyclopedias, on-line versions of major daily newspapers, or government-owned sites produce information as reliable as the material you would find in print. In contrast, unbranded sites or those generated by individuals tend to borrow information from other sources without providing documentation. As information travels from one source to another, the information has likely been muddled, misinterpreted, edited, or revised.
You can still find valuable information in the less official sites. Check for the writers credentials and then consider these factors:
|
|
|
- Dont let official-looking graphics or presentations fool you.
- Make sure the information is updated enough to suit your needs. Many Web pages will indicate how recently they have been updated.
- If the information is borrowed, see whether you can trace it back to its original source.

Because the Internet is a relatively new and quickly growing medium, issues of copyright and ownership arise almost daily. As laws begin to govern the use and reuse of material posted on-line, they may change the way that people can access or reprint material.
Text, photographs, music, and fine art printed on-line may not be reproduced without acknowledged permission of the copyright owner.
