1) Guessing URLs
If you're looking for a corporation or institute, start by guessing
once or twice what its URL (Uniform Resource Locator) might be.
Businesses spend a lot of money to have an obvious and easy-to-guess
URL, for exactly this reason. If you guess wrong, you'll be told
"URL not found."
- Assume the URL starts with "www."
- End the URL with the correct suffix, as
indicated
below.
.edu = educational institutions (www.wagner.edu)
.com = commercial businesses (www.nike.com)
.org = non-commercial organizations (www.pbs.org)
.gov = government organizations
(www.whitehouse.gov)
.uk, .ca, .nl = other countries have their own
suffixes (.uk - United Kingdom, .ca - Canada, .nl - Netherlands)
2) Use Web Site Listings
If guessing doesn't work, the next step is to go to a search site.
Web site listings are created by people who surf the Web for a living
and manually record Web sites. These Web sites are then categorized and
subcategorized into a hierarchy of sites.
You can browse through these categories and subcategories until you get
a listing of Web sites.
Web site listings are useful if you're looking for a site on a
fairly general topic, one for which there are hundreds, or even
thousands, of
Web sites. For example, by using selected listings for a popular topic
like "Star Wars" or "African bees,” you will avoid the unofficial and
not-very-good sites and find only the best.
Try clicking through this path on Yahoo! You will
end up with a listing of Star Wars sites:
Entertainment --> Movies & Film -->
Genres --> Science
Fiction & Fantasy --> Series --> Star Wars
There you'll find the listing of Star Wars sites, wonderfully
organized by subcategories (clubs, books, chats, screenplays, humor,
etc.). You'll find the official Star Wars site, sites by Star Wars
fans, and more.
You can also access the listings by using a search field. Try
typing "Harrison Ford" in the search field below and press Submit to
see the Yahoo! listings.
As you see on the top of the Yahoo! page, Harrison Ford is listed under
Entertainment --> Actors & Actresses.
Some Web site listings:
Yahoo! (www.yahoo.com)
Excite
(www.excite.com)
In addition to portal sites like Yahoo! that specialize in
search engines for the entire World Wide Web, many smaller sites
provide a sub-set of the Web, highly filtered for quality and
content.
While they can be very helpful, Web site listings don't always
work. It's much harder to search for specific information, rather than
a subject area. For example, if you want to find a calendar that lists
election days, then you might be better off with a search engine.
3) Use search engines.
Search engine computers search the entire World Wide Web and create a
huge, raw, and unfiltered listing of all sites, regardless of quality
or
type. When you submit to a search engine some words describing what
you're
looking for (keywords), it will provide you with a long listing of all
sites
related to your keywords.
Some search engines:
Google (www.google.com)
Alta Vista
(www.altavista.com)
Go.com (www.go.com)
HotBot
(www.hotbot.com)
InfoSeek
(www.infoseek.com)
However, if you're not specific or careful enough in your
request, you could be overwhelmed with thousands of links--and then you
won't know which ones to start with.
Conducting a Basic Search
Narrow your search with:
- Specific words
The simplest way to search is to type in a single word. If the topic is
narrow enough, that may be sufficient.
For example, "dysphasia" might work, but "cats" will give you too
many listings.
- Adding Quotation Marks
Quotation marks specify phrases instead of individual words.
Maybe you're looking for something that can't be
expressed in a single word, such as "Persian cats," "computer games,"
"drug therapy," "stock portfolio," "sports cars." If you type in sports
car (with no quotation marks), then you'll end up with a listing of
every Web site that has the word 'sports' and every Web site that has
the word 'car'.
When searching for a phrase, make sure to
enclose it in quotation marks:
"cross-country
skiing"
"early nineteenth century
literature"
"Jane Doe"
"Great Barrier Reef"
- Adding Plus & Minus Signs
The plus sign (+) requires a search function to include specific
words.
The minus sign (-) requires a search function to exclude specific
words.
A (+) guarantees that a particular word will be in all
the Web pages in your results listings. A (-) guarantees that a
particular word won't be in any of the Web pages in your results
listings.
- Capitalization
Capitalization makes a search case-sensitive.
If you capitalize letters in your search, then you
narrow the search to only occurrences of that word with the exact same
capitalization. If your entry is all lowercase, then the search engine
will search for
all occurrences of the word, regardless of capitalization.
The last thing you should keep in mind is that almost all
search sites have an Advanced link next to the Search field. If you
click on that, you'll be given ways to refine your search, such as by
date and language.
** Check the Internet
Public Library for comparison of search engine's capabilities.
How to recognize a good Web site from a bad one?
1) How did you hear about the Web site?
Is the site a brand name you're already familiar with? Was it
recommended by a reputable source, such as another Web site you trust,
a newspaper,
or magazine? Or did you simply stumble upon it while surfing? With
millions
of Web sites at your fingertips, it's wise to use a good filter.
ThirdAge.com, for example, provides Web Guides to sites we reviewed and
found to match our standards of excellence.
2) What's your impression of the Web Site?
Is it up-to-date and accurate? It is professionally presented
and maintained? Is a link to the individuals or organization behind the
Web site (such as an "About Us" link) easy to find?
If the site's creators don't want you to know who they are,
that's a warning sign. Likewise, look for links to biographical
information about the authors on the site. What are their
qualifications?
3) What's the purpose of the Web site and are they trying
to sell
anything?
You can start by looking at the Web site address. For example,
if the Web site is produced in the United States, it will likely end in
one of the following:
.com = commercial
.org =
organization
.edu = educational
.gov = government
.net = network
Always keep in mind the motivations of the Web site producers.
If you're getting health information from a Web site built by a
pharmaceutical company, then it's a good bet that the information may
be biased towards that company's products. Advertisements are to be
expected on any commercial site (just like you'd except ads in a
magazine), but it's essential to confirm if the editorial content is
fairly presented. In sum, what's the source of the information on the
site and is it biased?
