For quick and easy navigation, the pages are structured so that any entry can be accessed from the Home Page via usually no more than three links. If you jump to another entry via an hyperlink within a block of text, you may not know where you are exactly. In this case you can either go back to the NP Home Page or you can use the Back option on the Navigation Bar. Taking these options also aligns on the lower menu portion of the page, which is designed to save unnecessary scrolling. The NP Home Page obviously does not need the Back or the Home options.
Some hyperlinks are to pages outside thi site.
The pages have been designed to be viewed with a wide range of browsers. They do not contain Frames, but Tables are extensively used, so Netscape 1.22 or higher or Microsoft Internet Explorer 2.0 will work best. Browsers without Table handling, such as Lynx or Compuserve's early Spry Mosaic 04.00.08.20, will still display readable table text, but not in such an attractive form. It 's avaliable in the UK from Imperial College , or the Hensa Archives . Page top Tips for faster browsing.
