The lecture outlines are in Adobe Acrobat® file format. To read Adobe Acrobat® files the web browser you are using must have the Adobe Acrobat Reader available. On some computers, if the Reader is present, as you attempt to download the Acrobat file, the Adobe Reader will self-launch and you will see the contents of the file shortly. On other computers a dialog box will open that gives you the option of opening the file you are downloading; you should select that option and the Adobe Acrobat Reader will then open the file in the browser window. If opening the file in the browser is not an option provided by the browser's dialog box, but saving it is, save it to the hard disk and remember which folder or directory you placed it in. If you can find the Adobe Acrobat Reader on the computer, open it and click on the File menu, then on Open, and then select the lecture outline file you downloaded (it will have a .pdf extension in its name). If you cannot find the Adobe Reader on your computer, go here and download the reader that is appropriate for your platform (Windows or McIntosh, depending on the type of computer you are using). Double-click on the file you downloaded and follow the directions for installing the software. Once the software is installed you can launch the Acrobat Reader and use it to open the Acrobat (.pdf) files.
