I have been working at combing through my archives images. I always save photos by date. So I have complete sets of photos store in organized folders by day of the shoot, month, and year. I'll burn a data CD or DVD of the complete set before deleting everything but the chosen few.
I'm so glad I did it this way! Now I comb through these old data disks, reprocessing images, as well as gems I'd passed on the first time around. It also gives me a real sense of what I've been doing with my work.
Another benefit is looking at great old shots of my wife when we began this wonderful adventure.
