Have you discovered that you can also go back in time on google earth? There is a slider where you can go back as far as they have images. The base in Japan that I lived on as a kid and the surrounding town has changed a ton, but I was able to go back to 2003 and find one of the houses that we lived in that would now be in the middle of a road.

In Google Maps (Earth too, I think) if you have a login (any google login including gmail will work) you can put push pins with text and save that info. I've gone through the various places I lived and visited in Japan and Spain and around the US marking locations of jobs, friend's houses, places I worked etc... Some of the stuff required me to rack my brain to remember. Now, I can go back and tour places potentially years from now. I believe there's also some way that you can scan and upload pictures into google maps or earth, but I never really pursued that.
