Viewing PDFs (Portable Document Format)

Many documents in the website are in PDF format which means they can only be viewed using Adobe Reader. This software is available free of charge from the Adobe Web site. http://www.adobe.com/products/acrobat/readstep2.html

All PDF documents on this site will open in a new Web browser window. After viewing or printing the document, you can close the new Web browser window by using the close button at the top right hand corner.

The most recent PDF documents have been produced using the latest available version of Adobe Acrobat and following Adobe's guidelines on creating accessible PDFs. However, please note that some of our older archived Adobe PDF files may not be completely accessible when using screen readers. Adobe offers useful resources and tools to aid the accessibility of PDFs, these can be accessed via the Access Adobe website, and include a text-only Adobe Reader download page and an online conversion tool for PDFs.
