While this illustrated manual provides important technical information about the selection and preservation of memorabilia for an extended period of time, the reader is also introduced to a much broader understanding of "time capsules" and the significance they hold for human societies. With this knowledge, it becomes rather obvious that a time capsule is not a box to be unceremoniously dropped into a hole and accidentally discovered in the future.
