Using Adobe Acrobat (PDF files)

Some documents in this site are stored in Portable Document Format (PDF). This file format is used to store documents with complex formatting that the authors would like to preserve (typically text in several columns and mixed with a number of graphics).

To view and print PDF files, you must have Adobe Acrobat Reader (or an equivalent PDF viewer) installed: go to PDF reader to download the software.

Alternative ways to read PDF files

Adobe provide a free online tool which converts PDF files to text. You may find this useful if you use screen reader software or an audio-enabled web browser. To use this service, send the web address (URL) of the PDF document you want to read through the web form Online Conversion Tools for Adobe PDF Documents. The service will return the document to you as a web page (HTML) or as plain text. Alternatively, you can choose to get it emailed to you as an attachment.
