Adobe Acrobat Reader (PDF)
Description: Adobe Acrobat Reader is a program that allows users to view files in Portable Document Format (PDF). PDF is a universal file format that preserves the appearance of the original document. PDF files can be easily printed but not easily modified. Several documents throughout this Web site are available in PDF. These files contain complex documents with graphs, images, and special text that cannot be presented easily through the typical Web browser. The creator of this file format, Adobe® Systems, offers a free viewer so that you can view any PDF file.
File extensions: .pdf
Viewing: If you do not already have Adobe Acrobat, you can download Acrobat Reader for free.
