Many of the files on these pages are in Adobe Acrobat PDF format.  The advantage of PDF format is that readers are available for almost all common operating systems.  If your computer does not have Adobe Acrobat or Adobe Acrobat Reader, the reader can be downloaded free from Adobe.  Other files are available in Microsoft Word and PowerPoint formats.  These can be read by using MS Office on the Citrix system, or by downloading the PowerPoint Reader or Word Reader from Microsoft.  Note that installing software on college computers upsets the system administrators.  Obtain permission first.
