The It's About Time volume, which focuses upon the issues of historiography and chronology in North American archaeology, is the publication of the papers from a 1997 Society for American Archaeology symposium. The papers are for the most part on the development of various daring techniques (such as archaeomagnetism, dendrochronology, radiocarbon, or thermoluminescence) from an archaeological perspective, but there is one extremely thought-provoking critique by a social philosopher on how archaeologists "do" the history of archaeology, that for many readers may be the single most important paper in the volume.
