Library Resources Expanded On World Wide Web

If you have "surfed the Internet," now it is time to move on and "crawl the Web," that is to say, the World Wide Web. The Web is an information service providing links between the various computer networks on the Internet. Since its initial conception in 1989, the World Wide Web has continued to grow in number of sites to a total of over 15,768 as of March 1995 (December, John and Neil Randall. The World Wide Web Unleashed. Indianapolis: Sams.net Publishing, 1995, p. 1103)
WHY THE WEB?
Remember all of the commands you had to learn and type in to get to various Internet sites.' There were FTP Gopher, and Telnet, as well as. Archie and Veronica. The World Wide Web eliminates the chore of typing in commands. What the Web provides is a seamless, graphical, user-friendly way to tap the resources available on the Internet.
HOW DOES IT WORK?
The Web enables the user to do this through something called "hypertext" links. Hypertext is a way of linking documents using logical concepts across the Internet. Say, for instance, you are at a site on the Internet with these links reading an article about flowers. When you come to the individual flowers' names they may be highlighted. This indicates that they are hypertext links. If you want more information on an individual flower all you would have to do is to click on the highlighted name and you would be brought directly into a document held at another site with information about that flower. There would he no long addresses to type, no searching through directories to documents with Unix file names. You would be instantly in the document with the information that you were seeking.
These links can go beyond just links to individual documents. World Wide Web sites usually provide links to other sites with related information on the Web. This is one of the most exciting aspects of the Web because it leads to serendipitous discover!. It is so easy to wander from site to site, almost like browsing the stacks of a library. One interesting site usually leads to another. As you can see, using the Web can be habit forming, time consuming, and great fun!
HOW IS SEARCHING WITH THE WEB DIFFERENT?
Gopher, as compared to the Web, is set up more as a hierarchy. You go from menu to menu of directories and documents selecting the ones you want. On the Web the selection is more intuitive. Logical links have been established to information resources. You click on the highlighted word(s), and you are in the document you have selected. FTPing information requires looking through a directory of file names written in Unix code and deciding which ones you want to take back to your mail box. On the Web, clicking on a document name with a hypertext link established will bring that document to you.
SO HOW DO YOU GET ONTO THE WEB?
In order to use the graphical features of the Web, you will need a PC that is able to run Windows, preferably a 486 machine or a Macintosh computer. You also will need a special kind of software referred to as a "browser." A few of the current popular browser programs are Mosaic, Netscape, and Cello. What a good browser program will do is allow you to have access to sites on the Web while enabling you to continue to use the regular Internet utilities such as FTP, gopher, e-mail, etc.
If you have a PC that can't "do" Windows, don't panic! The Web is also accessible through a non-graphical browser program called Lynx. Lynx allows you to select the hypertext links in a Web document by using your cursor keys instead of a mouse. Lynx is available via anonymous FTP to ftp2.cc.ukans.edu. The files are located in directory: /pub/lynx. (December, p. 143).
 
You will also need a service provider that can give you access to the Internet and the Web. Computing & Data Services presents special Internet seminars on installing and using Enhanced NCSA Mosaic for University faculty and staff. If you want to access the Internet and the Web from home you will need to locate a service provider in this area. Two such providers are EPIX and the Internet Cafe.
WEB ADDRESSES
The addresses to Web sites are a little different from the usual Internet
address. A Web address is referred to as a URL: Uniform Resource Locator. A typical Web address would look as follows:
http://lcweb.loc.gov/global/www.html
 
The http refers to Hypertext Transfer Protocol. This part of the address allows the retrieval of documents from different sources on the Internet. What follows after the double slashes is the address of the Web site. The ending of this address html indicates that the document to be retrieved through the Web is in Hypertext Markup Language. This means that it will contain hypertext links to other documents and sites on the Web.
EVERY WEB NEEDS A SPIDER
Spiders are programs that "crawl" through the Web on a regular basis locating sites and creating subject indexes of their locations. When you visit a Web site with a powerful "spider" program it will allow you to query for information and then display the sites it has found. Besides spiders, there are also sites that are subject list indexes that have been handcrafted. These are good places to go if you are looking for documents on a particular subject matter.
INFORMATION ON THE WEB
With all of the information on the Web it is important to keep in mind that not all of the information one can retrieve is accurate or complete. Web and Internet resources in general are "not a substitute for a library or a good reference librarian." (December, p. 411) The Web, with its vast quantity of information, can be overwhelming. It also can he time consuming to try to jump from site to site to locate a piece of data. You can often save hours of frustration by visiting the Reference Desk of the library for your information needs!
