The library maintains a shared network drive of GIS data. The data primarily covers North America, but there is some South America data in there as well. This drive is also where you can find the tutorial data for the ArcGIS tutorials. The drive is called \\vuesri\\arcimage. For instructions on how to connect to the drive, click here.
The university also has a subscription to the ESRI Virtual Campus course through the site license. You can find a list of the courses here. Some of them are free, but contact me to get a keycode if you want to use one that is not.
