Introduction:
It is easy to get connected to Internet than to find out what one needs. Because the Internet was built by and for Sophisticated computer users it is not as user friendly as general user needs. The Internet is hard to learn for use, almost completely disorganized, there is too much of information and it is also growing too fast. There are some basic tools and utilities for working on the Internet and these are:
1) Electronic mail or EMAIL allows users to send messages
Finding the required information means finding out Web documents (a.k.a. Web "pages" or "sites") you want. It can be easy or seem impossibly difficult. This is in part due to the sheer size of the WWW, currently estimated to contain 1 billion documents. It is also because the WWW is not indexed in any standard vocabulary (unlike a library's catalogs which assign Library of Congress or some other widely accepted standardized subject descriptors to their documents, or a journal-article index which uses its standardized subject descriptors).
When you do what is called "searching the Web," you are NOT searching it directly. It is not possible to search the WWW directly. The Web is the totality of the many web pages which reside on computers (called "servers") all over the world. Your computer cannot find or go to them all directly. What you are able to do through your computer is access one of several intermediate databases and/or web-pages which contains selections of other web pages organized to allow you to find other web pages and sometimes other databases. You search these intermediate "search tools," and they can provide you with hypertext links (URLs) to other pages. You click on these links, and retrieve documents, images, sound, and more from individual servers around the world.
Categories of Search Tools Available:
1.Search Engines
1. Search Engines
Full-text of selected Web pages. Search by keyword, trying to match exactly the words in the pages. No browsing, no subject categories. Databases compiled by "spiders" (computer-robot programs) with minimal human oversight. Search-Engine size: from small and specialized to 90+ percent of the indexable Web.
Examples
: Alta Vista, Northern Light, Infoseek, Fast Search, Hotbot, Lycos, Excite
.
Meta-Search Engines quickly and superficially search several individual search engines at once and return results compiled into a sometimes convenient format. They only catch about 10% of search results in any of the search engines they visit.
Examples : Metacrawler, Inference Find, Dogpile, Metafind
This site has 900 Search Engines which are listed from around 59 countries:-

3. Subject Directories:
Hand-selected sites picked by editors, more or less carefully. These are organized into hierarchical subject categories. Often annotated with descriptions (not in Yahoo!). Are browseable subject categories or search using broad, general terms. NO full-text of documents and one can search only the subject categories and descriptions.
Examples : Librarians' Index, Infomine, Britannica's Internet Guide, Yahoo!, Galaxy, Scout Report Signpost, Looksmart, Lycos's A2Z and Top 5%, Built into Infoseek, Excite, Most university libraries maintained subject directories.

The Argus Clearinghouse, http://www.clearinghouse.net Searchable database of guides to subjects/topics, compiled by "experts" and reviewed and evaluated by Argus staff. Emphasis generally scholarly. Guides not maintained and revised are relegated to a sub-list.
UCB Internet Resources by Subject, http://www.lib.berkeley.edu/Collections/acadtarg.html Many links to Internet resources on many academic disciplines selected by UC Berkeley Library subject-specialists.
WWW Virtual Library, http://conbio.rice.edu/vl/database/ Browse subject list of subject guides, prepared by individuals all over the world and mirrored in this list at Stanford, Fisk University, and elsewhere. You may try searching from the box on this page, but often browsing finds pages the search does not.

5. Subject Databases available via WEB.
The Web provides access through a search box into the contents of a database in a computer somewhere. Can be on any topic, can be trivial, commercial, task-specific, or a rich treasure devoted to your topic. Locate by special guides to databases, in Librarian's Index, Yahoo!, and sometimes by keyword searching general search engines. Databases exist on all sorts of topics and for many purposes (social, scholarly, scientific, research, legal, commercial, trivial, ...). Keep your approach VERY broad and general.
Example:
Search.com,
http://search.cnet.com
Very convenient, searchable collection
of searchable databases. Very worthwhile for many topics and for reference.
Overlaps somewhat with Internet Sleuth. In lower yellow area (not the top
box on the home page, which is general web searching), select a subject
category. You may enter a search directly from the resulting Search.com
screen. OR, search using keywords on your topic. Scroll down below
the list of subject categories on the home page and click on
Find a
search (keep searches very broad and simple). OR, click on
A-Z
list to see an alphabetical list of everything available through Search.com.

directories, meta-search engines, and tools to find media, geographic-based
sites, reference sites, software, music, art, education, technology, politics/government,
hobbies/games, and more. Browse categories to the left, especially the
broad subjects toward the bottom.

Consult the Databases
retrieved
from any broad subject search. Search Yahoo!, http://www.yahoo.com/
for directories and search tools in specialized subjects. In Yahoo!
search box, search for the phrases-in-quotes: "searching the web" "search
engines". In Yahoo! search box, search for the phrases-in-quotes: "searching
the web" "web directories" Search Yahoo! for the phrase-in-quotes "searching
the web" and then
sub-search on the results page, restricting
to search only in "web searching" for any topic you wish (e.g., women,
business, stocks, music, environment...)

6. Locating Peers and Experts through online discussion groups
Newsgroups (a.k.a. Usenet) are accessed and viewed on the WWW. Netscape supports viewing Newsgroups. Although some academic disciplines prefer Newsgroups over Listserv-type e-mail groups as their scholarly forum, Newsgroups tend to be popular, fun, alternative.
Example:
Deja.com (a full-text search tool), http://www.deja.com -- a specialized database just for searching Newsgroups. If you direct searches to "newsgroups" or "usenet" in any of the major search engines (like Infoseek, Hotbot, Excite) you are searching the DejaNews database. It is easier to search directly from DejaNews. Alta Vista alone has its own newsgroup database. SEARCH TIPS(some of the many options): Browse by subject category or "community" at left. Search for terms in newsgroup discussions or communities in the search box. Power Search allows you to search on authors' names and other fields. Be prepared to read a lot of help screens and spend time getting up to speed in the world of searching for and using Usenet Newsgroups. Try the User Tour.
Mailing List Finding Aids (such as Listserv® lists) Mailing lists work through your e-mail, not on the WWW. You subscribe and receive mail from the group.
7. Finding Individual People's Pages and E-Addresses

Ahoy!,
http://centauri-prime.cs.washington.edu:6060/
