There are also a large number of 'pdf' format files on the site, which can be viewed with the Acrobat 'plug-in' from Adobe that updates your browser. Pdf files are popular on the World Wide Web as a whole, and so getting this upgrade should enhance your online experience in general. Best of all, the software you need is free.

If you have a really old 'version 2.x' browser, you may wish to upgrade to a 'version 4.x' (or 5.0) browser in order to get the most benefit from this site. If you have one of the 'version 3.x' browsers you do not really need to upgrade, but you might consider upgrading anyway if you frequently enjoy using the World Wide Web. Popular browsers from Microsoft and Netscape can be downloaded via the links below. (Note: browser software is usually much larger than 'plug-ins' like the RealPlayer or Acrobat products. Plan the download and installation process to take at least an hour or two, longer if you have a 14.4k modem).
