Scattered throughout the website are links to files for you to download onto your computer and read offline. Here's how to work with those files.
PDF documents are in Adobe's proprietary Portable Document Format. They contain elaborate formatting, graphics, and custom fonts. They often look more "polished" than do run-of-the-mill web pages — especially when printed.
If the file doesn't open automatically after downloading, double-click on it. If that doesn't work, get a copy of the free Adobe Acrobat Reader software.
Zip files contain an archive of one or more text files that have been compressed to reduce download time. If the archive doesn't un-zip automatically after downloading, try double-clicking it. If that doesn't work, you may need to get an inexpensive utility program to un-zip it. Here are some suggestions:
After you un-zip the archive, the files it contained will appear in a folder on your hard disk. If these files are HTML files, simply open them with your Web browser program. If they are text files of some other sort, open them with your favorite text editor.
