Another surprise was the amount of notecards that are associated with one another. While some cards contain a short one-line joke, other jokes span several cards. These collections of cards had originally been paper-clipped together, but at some point in the life of the gag file the paper clips were removed. This removal was great in terms of preservation because paper clips tend to rust and cause damage to the surface to which they have been attached. But the removal also made it difficult to decipher which cards were originally associated with one another. I was able to use the bend marks on cards as well as rust marks from where a paper clip used to be to record which joke cards were most likely originally paper-clipped together. This association is important to note because some individual cards only hold a portion of a longer joke and therefore do not make sense independently.
