<p>I'm chiming into this discussion late, but it's been fascinating to scan through. I'm sure that photos are important in different ways to different families, and whether they survive is largely dependent on the passion of one or two people along the way. In our family we've expanded the overall "library" to 10's of thousands, and because I care, and one of my cousins cares, we've been able to keep a well-organized, searchable approach that allows anyone to go back in the 1800's to get photos of an individual or family grouping. But we've also kept the photos of trees and rocks that mattered to various people along the way, and those are apparently important to some other individuals in so far as they show what was important to that photographer. We've published a couple of books using the photos, and all in all we have more of a sense of family than we had before the digital age as a result. </p>
<p>But it does come back to someone caring enough to make the effort - in our case thousands of photos that were on their way to the usual fate have been preserved, and are used. Will that last into the next generation? Maybe, maybe not. Not my problem - someone else will have to decide if they care enough to make this a family tradition.</p>
