List-making: a peculiar yet familiar inhabitant of so many archival collections. Umberto Eco loved list making. So did Susan Sontag. It is human nature — to create a list, to make a secret promise.

In that particular collection, there was an impressive volume of lists all containing the same repeating reminder: don’t forget to pick up pants.
