Our most sincere gratitude is due to Dr. Shneiderman, whose comments, suggestions and feedback at all stages of the project proved invaluable to us. We would also like to acknowledge Dr. Berlin and Dr. Schulman from the Department of History, who allowed us to use their class time to talk to history students about the American Memory site and request them to participate in our experiment. Moreover, we are indebted to all the participants who took the time to participate in our experiment and provided us with the opportunity to conduct this study. Finally, we do wish to thank all our friends and family members who took interest in our project and provided us with feedback and suggestions.
