En passant: this fabulous hoard of family photographs reminds one that most people living today will leave nothing like this because their digital photographs will be on computer disks or hosted on online servers. Which means that when they die, most of those accounts will be closed or inaccessible to relatives, and the images will therefore be lost to posterity. Which is why, when people ask me about digital preservation, I tell them to print anything they wish to preserve and store them in shoeboxes in their attics. That’s the only way their grandchildren and great-grandchildren will ever be able to see them.
