The "back" button will take you to the previous page you have viewed.
The "forward" button will take you to the next page on your path (will only be active if you have already used the "back" button: the computer can’t guess where you would go next).
The "reload/refresh" button goes out and gets the most recent version of this page.
The "home" button takes you to whatever page is defined as "home" on this machine. If you are using Netscape, you can set "home" in your Preferences. If you are using Internet Explorer, you can set "home" in your Internet Options.
Suppose you have an address of http://www.uky.edu/Libraries/Tour/Quilts/east.html.
The first part before the colon is called the protocol and tells your computer how the information will be transmitted. In this case http, or hyper text transfer protocol, is the protocol. The next part, after the double slashes and before the first single slash, tells it which machine on the Internet to connect to, in this case, a machine at the University of Kentucky. The machine does not have to have "www" in its name, the UK’s web-based library catalog is at http://commonweb.uky.edu:8000/.
The rest of the address is called the path and tells your computer to look in the Libraries directory, and find the Tour subdirectory, and the Quilts subdirectory of that, and find a file named east.html there. If this didn’t work, and you get a "file not found" error, you might try copying the address, and look at http://www.uky.edu/Libraries, to at least get the UK Libraries page.
