Accessing downloadable documents such as reports and committee papers

A large number of documents are available for download from this website. Wherever possible, these documents are made available in two file formats - Portable Document Format (PDF) and Rich Text Format (RTF).

To view PDF files you must have PDF reader software, such as Adobe Acrobat Reader, installed on your computer. This software is available free of charge from the Adobe website. Users with visual impairments who make use of text to speech software may encounter problems when using PDF files. The website provides tools and information to help make PDF files accessible to users with visual disabilities. Information about alternative PDF reader software is available at

Wherever possible, we provide RTF files as an alternative to PDFs. RTF files are readable with most current word-processors. Please note that the RTF files may not maintain the original formatting and layout of document and that images - pictures, maps, graphs, logos - are removed. RTF files may be larger than PDFs and therefore slower to download.
