With each passing of a generation, millions of human memories and experiences are lost forever. Efforts to preserve these stories through oral histories are popping up in towns and cities across the nation. In Rocky Hill, Conn., the town's human services department is offering such a program to homebound senior citizens, helping them record their oral histories to be shared with their communities and future generations. Only two seniors have participated in the program so far, but each said they found it therapeutic, and listeners reported discovering family and American history they'd never heard before. The program began earlier this year when the town purchased new audio recording equipment and trained volunteers to conduct interviews. On a similar note, Idea Center featured a program last November in Georgia, created to collect and preserve photographs for its archive's permanent collection.
