The World Wide Web

Many students prefer to use the Internet for all of their information needs.  But the Internet is limited.  Many sources of information online are password -protected and cannot be located by using a search engine like Google.  This is what we call "The Deep Web."  Here at Sonoma Valley High School Library, our digital sources of information are purchased through EBSCOhost and require a password to log on.  We'll get to these great sources of information shortly.  Some general background on the World Wide Web may be useful:


The World Wide Web (WWW) and the Internet are not the same.

The WWW is a component of the Internet that presents information in a graphic interface. 

The WWW is an illustrated version of the Internet


The Web was text-based until 1993

The World Wide Web began in the late 1980's when physicist Dr. Berners-Lee wrote a small computer program for his own personal use.  The program allowed pages, within his computer, to be linked together using keywords.  It soon became possible to link documents in different computers, as long as they were connected to the Internet.  The formatting language that Dr. Lee wrote was called HTML (Hypertext Markup Language). 

As long as a person knows HTML or knows how to use an HTML editor, they can put any kind of information on the Internet.  This is both good and bad.  As a student conducting research, it is important to know how to tell if the information online is accurate or not.
