PDF is the file format used extensively on the Internet to display non-HTML documents. With a PDF file users can browse, print and download documents as they appear in their original format. A free Acrobat Reader "plug-in" is required to view and/or print PDF files. If a document does not appear after clicking a link labeled PDF, then you need to download the current version of the Acrobat Reader by clicking on the Adobe "Get Acrobat" Reader icon below. Please note that you'll be downloading Acrobat Reader from the Adobe website to the hard drive of your desktop PC. If you successfully install Adobe Acrobat Reader and it does not automatically launch after you select a PDF link, you may need to modify your browser's preferences.
