Washington - Most of us have a box or book of old photographs somewhere - precious memories of times and people we hold dear.
Thanks to the paper on which those photos are printed - and the ease with which paper can be handed down - those memories are intact.
But what about future generations? If we copy our digital photographs, video, or sound clips onto CDs or DVDs, will our heirs even have the equipment necessary to read them?
It's a question that deserves careful consideration, especially since many of us today are spending countless hours amassing irreplaceable memories and, for the first time, entrusting those memories to various forms of media that are not only fragile but can also quickly become obsolete.
