Dear Patricia

I am the director of Antenna Audio Tours, a non-profit company which
produces audio tours for museums and historic sites.  In the last six
months there have been two extensive evaluations on our portable CD-ROM
audio tour system, the Gallery Guide.  The most recent is by Margaret
Menninger, who studied 200 GG users at the Museum of Modern Art in San
Francisco.  Earlier this year Ellen Giusti at the American Museum of
Natural History completed a similar study of Gallery Guide users.  Both
studies provide a very helpful analysis of usage patterns, ease of use,
and educational effectiveness.  I will send you copies of the studies.

Others who are interested in the study can contact me here or at Antenna
PO 176

Best of luck with your research.
