What is PDF?

PDF stands for "Portable Document Format." It is a technology developed by Adobe based on a language called Postscript. PDF preserves the original look of the document almost exactly: fonts, photos, graphics and layout all appear as they do in the original.

Anyone with the right software using Apple Macintosh, Microsoft Windows (3.1, 95, 98, Win2000, WinXP), Windows NT, and Sun and Hewlett Packard workstations can view any PDF document. In addition, files that are described in Postscript can be printed on any printer that speaks the Postscript language, regardless of what kind of computer is connected to the printer. Likewise, regardless of what type of computer creates a PDF file, it can be viewed on any computer with Adobe Acrobat software.

In order to view PDF files, you must use PDF-reading software.
Download Adobe Reader - it's free!

The PDFs on our site require version 5.0 or better.

The Reader can read any PDF document, not just those served up by the browser. Once the Reader is installed, it works seamlessly with your web browser (if you have the most recent version of your browser)--in other words, there's no jumping back and forth between programs. In addition, the software will allow you to begin viewing the document before it has finished downloading.
