Pages on this site use valid HTML and CSS, as validated by the World Wide Web Consortium (W3C).
Downloadable files from this site - for example, Adobe PDF files - may present accessibility problems.
PDF files are universally readable on any platform but require a piece of software called Adobe Reader. This may already be installed on many machines, in which case simply clicking on a PDF link should open the file. If you do not have Adobe Reader on your machine, it is available from Adobe as a free download (this link will open in a new window).
