This thesis critically examines public communication in public archaeology, focusing specifically on benefits communicating provides to archaeology and to the public, obligations public archaeologists have to communicate, and methods of communicating. Although calls for research on public communication and discussions of the integral role communication with the public plays in public archaeology are common, few examples of such research exist. Moreover, it is argued that public archaeology lacks theoretical foundations, which are best developed through research of specific areas within the discipline. Accordingly, this study provides data that address public communication in public archaeology and these fundamental problems through a web- based survey of professional archaeologists, public archaeologists, and those in related fields. Through such research public archaeology can move beyond mere practice, while addressing one of the most important issues in public archaeology and developing practical recommendations for more-effective communication.
