Many of the AHEC digital documents, images and photographs are available for viewing over the internet in Adobe's Portable Document Format (PDF). In order to view these items you will need to download and install the free Acrobat Reader version 5 from Adobe (www.adobe.com). You will then need to configure your browser to run the Adobe Reader or PDF Viewer as a "helper application". This performs best with Netscape version 7 or later for the Macintosh.
