Katy:
 
          It sounds as though you are specifically interested in art
          museums, but...
 
          The New York Botanical Garden has been offering education
          programs since roughly the turn of the century. We have an
          archive that is incredibly comprehensive, and some good
          searching aides. So, if you were interested, you could make
          a pretty interesting study of the evolution of these
          programs.
