The recent commemoration of Anzac Day’s 100th anniversary was as good a reminder as anything of the importance of keeping records of our history. Photographs from that time may be grainy, blurry and often creased, but they still manage to provide incredible insight into a very different time. This, of course, is even more important now as there are no remaining survivors of that campaign – pictures and words are all we have left.

Which begs the question. In another 100 years, what memories will today’s generations have left to share with our counterparts of the future?

On the surface this seems a ridiculous question. After all, we take billions more photos and write trillions more words today than were collected in the early 20th century. But it’s not that simple. There are two major problems, both relating to the fact that so much of what could be ‘tomorrow’s memorabilia of today’ is not stored in permanently useful formats.
