Kathryn,

This type of work is basic GIS work that should be able to be achieved 
without resorting to scripting. That is, achieved through a simple GUI 
interface using preconfigured tools. The issue is whether you actually 
have land use and land cover data for the 1990s.

Present the same inquiry to an ESRI forum - you would probably have more 
chance of a response. If your University does not have the entire ESRI 
suite you can download any number of free and open source tools that can 
do this work -- e.g. GRASS, gvSIG, QGIS. All you need to do is convert 
the ArcMap file to something that can be used by ArcView or by one of 
these tools (e.g. shapefile).
