A few things to keep in mind when searching the Web:
It's huge. And growing rapidly. The result is that it's a body of information (I didn't say "knowledge") that has no index or table of contents. Or incomplete ones, at best.
Nobody has figured out any way to calculate accurately the Web's true size. Estimates in the summer, 2001 suggested that it may be as large as 2 billion pages. (That's 2,000 million for some people.) As at December, 2002, Google claimed that it has 3 billion pages to draw from but not all of those pages are indexed. AllTheWeb claims to have indexed over 2 billion pages.
Many search engines do their own indexing, using "webcrawlers" that go out and report back what they find. The result is that each has indexed different portions of the web, and AltaVista may therefore have pages indexed that Google doesn't, even though AltaVista's index is a fraction of Google's. Meta-search sites and search portals therefore may have an advantage in finding stuff, but can be slower and/or deliver incomplete results because of time-outs.
Part of the problem is that the web is simply growing and changing so fast that the webcrawlers can't keep up. And there is a significant (and growing) portion of the Web that isn't visible to the webcrawlers. That stuff is sometimes known as the "invisible Web" or "dark matter". It's composed of stuff that can't be directly indexed, like graphics, CGI scripts, Flash and Adobe Acrobat files, and database data that is assembled "on the fly" in response to specific requests.
The multiple- and single-engine websites below will help you search the "visible" Web. For a useful guide to the use of those search engines, go to Okanagan University College's "Sink or Swim: Internet Search Tools & Techniques" page. Or check the collection of tips at
Search Engine WatchFor some comments on when to avoid the major engines, read ZDNet's "When to Fire Yahoo and Alta Vista (And Who to Hire Instead)" re industry-specific or specialty search engines.

And which is the best search engine? It depends on what you're looking for. The bolded names are only my own preferences in the category shown. The descriptions provided may help, but they are far from complete. Many sites listed below have more than the capability suggested by the category they are in that's only because they are listed in the categories they are best at.
If you want your search engine to provide particular functions for your searches, the "search engine selector" at SelectSmart.com may help you choose the engine that best meets your needs. NoodleQuest will do the same, but based on particular search needs.
For search engine ratings and more information about Web search engines, try these sites:
- Omnibus Search Sites
- Multiple-Engine Resources
- Single-Engine Resources
- E-mail & Web addresses
- Image Databases
- ListServs
- Resource Locators
- Software Search Utilities
- Usenet Searches
The portals allow you to plug a search term into one of several search engines without actually having to go to that site. Some will enter your search term into all of the engines provided, then wait for your order as to which engine(s) you want to use. These are particularly useful if you want to search several sources separately.
The links pages work just like this one. They provide
links to a variety of search engines. They all vary in their content. Use
one of these if you find a dead link below it might have a more up-to-date
link.
This category seems never to have caught on. There used to be more clearinghouses listed here.
Don't assume that the lack of indication of any
cost means it's freeware. Sometimes the shareware registration fee is not
disclosed by the repository, and you don't find out about it until you've
unpacked the download.
Some of these sites maintain copies of shareware
and freeware software on their own servers. Others redirect your download
request to the publisher's website, so you get it direct. Some would suggest
that a file obtained directly from the publisher is less likely to have
been messed with. Regardless of the source, anti-virus precautions should
always be taken. Links to further information on that topic can be found
on the anti-virus information page on this site.
E-mail & Web Addresses
If you're looking for snail-mail addresses and
phone numbers, go to the Directories
section of this website.
Image Databases
Image search engines do just that -- they index images.
Trouble is, indexing is a bit subjective, so your mileage may vary.
ListServs
Listservs are the systems that handle e-zines and
e-mail discussion groups. They're usually free. More detailed information
on how they work can be found at this
page. The sites listed below will help you find an e-zine or two that
deals with your areas of interest.

Software Search Utilities
There is a great deal of software available for downloading
from the Internet, whether as freeware, shareware, or "buy-before-you-try".
In general, freeware is copyrighted, but no payment is required. Shareware
is bought on a "try-before-you-buy" basis; if you decide to use it, you
are obliged to pay a registration fee to the publisher of the software.
Usually, nothing is paid to the site from which you download shareware.
Some shareware includes enforcement provisions it will disable itself
if it remains unregistered past a certain trial period, or will nag you
to death. "Buy-before-you-try" is the same as commercial shrinkwrapped
software, except that there is usually a saving because the manufacturer's
distribution costs are significantly reduced and there is no printed manual.
Both are expensive for the software publisher.
