Fortunately, you can uncover this wealth of information by using
specialized tools designed to mine databases. For instance, let's say
you want to buy a used copy of "Alice in Wonderland." How would you find
it? Searching on eBay or Amazon.com--essentially querying their
databases--will be more fruitful than using Yahoo! or Google. The same
goes for job hunting. Since job postings are stored in a database, most
search engines can't find them; searching sites like Craigslist or
Monster is a better way to go.
The secret to successful searching is to understand what you want to
know, and then using the right Web resource to find it. Ask yourself
these questions:
- Is the information time-sensitive, such as stock quotes or newspaper articles?
- Are you looking for a photo or a video clip?
- Do you want to find an MP3 music file or listen to a podcast?
- Are you searching for specific types of content, such as blogs?
If the answer is "yes," then try using the tools listed in the chart
below. And when you find ones that you like, be sure to bookmark them
for future use.
