I would export to Word and import into ID. However to be truthful, you 
are barking up the wrong program. For something as long as a college 
course catalog, I would recommend FrameMaker. Its cross-referencing and 
long document capabilities are unbeatable. With the combination of 
Robohelp in the Technical Communications Suite, you could get a nice web 
version of that catalog up and running and keep them in tandem.

Frame's conditional text features would made producing multiple catalogs 
a snap. This would be helpful for example if you had several different 
graduate catalogs for different divisions. I'd consider ID for a school 
of graphics design, but for traditional colleges, I'd go with the TCS.
