The files above are PDF's (Portable Document Format). PDF's allow you to view and print documents even if you don't have the application that created them. To use these files, you must have Adobe Acrobat's Reader, available free on the web from here.
Once you have downloaded and installed the Reader, click on the file you would like to view. The document will come up in one of two ways. Either Acrobat will automatically open a window so that you can view and print the file if you choose, or you will be asked to save the file to your hard drive (remember where you saved it!). If you save the file to your hard drive, simply double-click on it's icon and it will open automatically.
