I work at DeLorme and saw your post. I have been visiting colleges with my son and was pleasantly surprised to see that I could find them all by simply typing the name into the QuickSearch Find. Both Harvard and MIT are there (as well as labelled on the map) in Street Atlas USA 2006 so you must be doing something wrong. Please try again.
Also of possible interest,in the Map Features tab of the new Options box along the top toolbar in SAUSA06, you can turn on and off various features, including minor places of interest. We allow this to let people clutter or declutter their maps based on their own preferances.
Hope this helps.
