About PDF Files  

Downloadable documents are in Portable Document Format (PDF). These files can be viewed, saved, and printed in identical form on most computers. Adobe Reader is free software for using PDF files. If it is not installed on your computer, you can download it from Adobe Systems. For those who use screen readers, recent versions of Adobe Reader include text-to-speech and other accessibility functions, and Adobe provides online tools that convert PDF files into HTML or ASCII text.
