Persistence of memories

I found myself concerned about the permanence of this diary, while looking at my great great grandfather’s civil war diary. You see, I still have that, and can know what he did on particular days during the 1860s. But as I write this diary, it is very uncertain whether my great great grandchildren will have access to this information. Not that it seems important now, but I suppose it seemed rather unimportant, at the time, that Isaac Nace heard guns from over in Gettysburg.

Yes, I have backups, but what good will CDs and floppies be in 2140, I wonder? I should probably start printing this stuff out, and putting it in a binder of some kind, just out of courtesy to my decendents.
