This article presents critiques and analyses of recent work in digital public archaeology (DPA) in the United Kingdom. It first locates different strands of DPA within the wider field of public archaeology, and begins to map out the diverse forms, aims and sources of DPA. Next it critically examines the models of 'communication' that are present in DPA, suggesting that greater attention should be paid to audiences in particular, and monitoring and evaluation in general. Finally the article considers the democratising effects of digital media on archaeological knowledge economies, highlighting some current and potential future areas of interest.
