Pieces of paper can get lost, spilled on, and destroyed in several ways. But for some of us, paper is still where we take notes, make comments, etc. Always save digital images of those paper notes that you make. The notes on the page in this illustration are for my own personal use–there are no citations or any of the other niceties that genealogists need. I was simply trying to sketch out the family relationships for my own personal, internal use.
Yet I don’t want to have to repeat that process and I may want access to those notes later when my files are “not handy.” A digital image is a great way to do that.
Just make certain you get the whole page when taking the picture.
