Apart from the first and last pages in the sequence each page will have a predecessor and a successor - it's 'neighbours'. The navigation menu also has a link to the home page. You may notice that if there is no previous page then the left arrow button is omitted. Similarly, if there is no next page the right arrow button is omitted. The placement of the navigation menu at the top right and the navigation buttons at the bottom right means that minimal mouse movement is required when browsing my pages.
Most browsers also have the ability to scroll down a page at a time at each press of the space bar.
This image is, in fact, a client-side imagemap and if your browser supports these you will be able to navigate to the home pages of the Department and the University by means of the hot spots. In the top right hand corner of each page is a reference to the actual URL of the document. This is much harder to explain than it is to see it in action so just check it out. In actual fact these links are relative URLs which means that the web pages can be rendered to a local hard drive and the navigation between them is as if they were on the web server. There is another instance of the navigable URL in the footer of each page.
