(Many of these materials are in PDF format. In order to view a PDF file, you have to have a program that can read them. The standard for many years has been Adobe Reader. You can download that directly from Adobe by clicking here. But many people (including me) have found recent versions of this program to be both "buggy" and outrageously bloated and slow. Another program you can download for free is Foxit, available by clicking here.)
