You have sorted through the family papers that were in your grandparents’ home. You have found precious documents – birth, marriage, and death certificates, diaries, letters. What do you do with them all?
First of all, make a copy of them. A photocopy will work. Then, what about scanning the item (could this be done at the same time a photocopy is made?). Saving a copy on your external hard drive and “in the cloud” will assure that you always have a copy.
If something does happen to the original, you will at the minimum have a copy. Your descendants will thank you!
