Many of the files on this site are in Adobe Portable Document Format (PDF).
This does mean you will need the Acrobat Reader software installed on your machine to be able to view them.
When opening links to the PDF files, they will normally open inside the browser window. Some of these files are quite large and if you would therefore like to save them directly to your own computer, follow the instructions below.
This tip also works with any other downloadable file on the site.
The Acrobat software is distributed widely on computer magazine cover disks and with software, but can be downloaded from the Adobe site by clicking on the image.
Further information about the Acrobat software can be found on the Adobe web site.
