Do you have old family photos and documents sitting around in a box in a closet somewhere? I guarantee that even if you're not interested in them, someone is! Please either scan them in to your computer or contact your family historian (If you're related to me, that would be me!) and get them scanned in.
Why do I feel it's important? I have two good reasons. First, to share the old family photos with others in the family! In the past, you'd have to worry about the price of duplicating a photo and physically sending a copy to whoever would like a copy. Now, the only cost is your time. The second reason is to preserve history. What would happen if tragedy happened and you lost your house to fire, flood or tornado? Those family photos would be gone!
Finally, once you get them scanned in, make certain to back them up!
Write them to a CD or DVD and mail them to other family members! Put
them on a blog or website! What I do is use Bittorrent Sync to
automatically back up my family history documentation folder to
relatives who volunteer to be the backup location in order to also have a
copy of it. You can see my writeup about this program here.
I enjoy bringing my flat-bed scanner to relatives' houses and scanning in their old photos and documents. As I scan them in, I create a text file documenting who is in each photo. This way I can document who they are as I enter them into my family history database.
