I think you need to keep *everything* for posterity but I suffer from having enjoyed the glories of unearthing 1920s dance programmes, the Air Raid Warden helmet, my grandmother's love letters, and 1950s dresses as a child in the house in which nothing has ever been thrown away. And when my mother did throw something away it was the 1950s dresses that we used to do dressing up in and we are all now really cross about her having got rid of them. This is not helping.

But it is good that you are applying yourself to the task at hand. Slowly is better than "empty all boxes out over the floor in fit of zeal and enthusiasm, then hide, daunted, from the ensuing insurmountable chaos"
