Digital Public Archaeology is a very new label for a contemporary practice, and as such has been subject to a limited amount of theoretical scrutiny. The rapid pace of change within Internet technologies has significantly expanded potential for this ‘digital’ form of Public Archaeology practice. Internet technologies can be used to gather contributions of ‘crowd-sourced’ archaeological content; to share and discuss archaeological news and discoveries; foster online community identity, situated around the topic of archaeology and wider heritage issues, or to elicit financial support. Expectations of and opportunities for social, collaborative and individual participation and interaction with cultural heritage have grown accordingly. Professional archaeological organisations are increasingly encouraged, if not required, to disseminate their grey literature reports, publications, educational resources, data-sets, images and other archaeological informatics through digital means, frequently as mandatory outputs for impact assessment and public accountability. Real-time sharing, comment and feedback of archaeological information online and via mobile technologies stand in contrast to lengthy waits for publication and wider dissemination. This paper will explore the literature on the practice of Public Archaeology in the UK, and issues associated with the development of digital public engagement in the heritage sector.
