Update: I decided to store them in just a few family group albums. I got acid-free sleeves online & put all into those for safe long-term storage. Plus one A3 size acid-free portfolio for supersize items. Think that will work best.
I decided to take lots of old family photos out of picture frames (never displayed) and put them into albums. Also includes some photos & documents lying around not in any album but that I want to keep.
Some items are over-sized and will go into an acid-free portfolio (A2 size?).
I can't decide what's best with others. Do I just sort them into albums in approx date order, making up as few albums as needed OR
I could sort by generation, by family branch, or even a selection of photos from each family branch into 4 different albums, one album for each of my 4 DC to inherit one day.
What do you think, what would you do?
ps: most have been scanned in already, and I like keeping old photos, especially ones back to early 1900s or earlier.
