If she has several large boxes and you are hoping to make one or two albums, I would suggest maybe going with a plan, who are the people you want to know about most, what do you want to know about them, make a list of those things you would like to document, and try to search out those pictures,take a tape recorder Grandma may remember some great stories going through pics, You can buy a special pencil that will allow you to write on the backs of the photos without damaging the image on the front. good luck with your project!
