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).
