Some documents are published in Adobe Acrobat's Portable Document Format (). You should be aware that documents held in this format are typically much larger than simple text files. If you are connected via a slow modem over a telephone line, you should consider the likely download time before attempting to retrieve such documents. In order to help you decide, we will give the size of the PDF file alongside its description.

Visually impaired visitors to our website can use Adobe Acrobat's online conversion tools to convert documents into HTML or ASCII text.
