The Internet is a system of protocols (a protocol is a specified means of communication) which allow networked computers to communicate transparently across multiple, linked packet networks. These protocols are known as TCP/IP (Transmission Control Protocol and Internet Protocol) and are comprised of telnet, email, ftp, http, USENET, gopher, and others. These protocols allow thousands of different types of computers linked to the Internet to speak to each other. Packet switching forces the information request into packets (or small chunks of information), each packet being sent along the least busy segments of the network and reassembled into a full document when it reaches its destination.
The World Wide Web (WWW) or “Web” is really a subset of the protocols that make up the Internet. The Web protocol is called http, it uses html coded “pages”, and is a distributed hypermedia system that allows distribution not only of text, but of graphics, sound and animation. It is a network of information within the network of the Internet. The Web uses a hypertext system to make navigation of that information possible. When a document is displayed, words on the screen may be linked to other locations in that document, or to other documents or sources. To see information on the Web, you must know an address. This address is referred to as a URL (Uniform Resource Locator) and is in the form of http://www.asbury.edu/ In order to view these pages on the web, you need a browser (such as Netscape, Firefox, or Internet Explorer) which will format the coding of the html into a layout that is readable by a person, viewable on a computer screen.
When you “search the web” you are actually searching this smaller segment of the total internet comprised of the html coded web pages. While the amount of information contained on these pages is very large, it is not the total amount of information that is available. Everything is NOT on the internet or the web. What is available on the Internet is often what can most easily be translated into electronic form, which is not the same as the best information. Numbers, statistics, facts, etc can easily be loaded onto a computer. However, carefully researched, thoughtful scholarship takes longer to produce and is not as likely to make it to the web.

Don't assume you know what you want to find. Look at search results and see what you might use in addition to what you've thought of.
Switch from search engines to directories and back. Find specialized directories on your topic. Think about possible databases and look for them. Ask for help from knowledgeable librarians.
