This paper considers recent attempts within archaeology to create, integrate and interpret digital data on an unprecedented scale-a movement that resonates with the much wider socalled 'big data' phenomenon. Using the example of our work with a particularly large and complex dataset collated for the purpose of the English Landscape and Identities project (EngLaID), Oxford, UK, and drawing on insights from social scientists' studies of information infrastructures much more broadly, we make the following key points. Firstly, alongside scrutinising and homogenising digital records for research purposes, it is vital that we continue to appreciate the broader interpretative value of 'characterful' archaeological data (those that have histories and flaws of various kinds). Secondly, given the intricate and pliable nature of archaeological data and the substantial challenges faced by researchers seeking to create a cyber-infrastructure for archaeology, it is essential that we develop interim measures that allow us to explore the parameters and potentials of working with archaeological evidence on an unprecedented scale. We also consider some of the practical and ethical consequences of working in this vein.

This paper initially presents a set of density models for England constructed by the members of the English Landscape and Identities (EngLaId) project and then goes on to discuss three possible explanations for the variation seen: modern affordance, variability in past usage of material culture, and past population density. The various members of the project team (with the aid of Andrew Lowerre) then provide their thoughts on the models and ideas presented from their own specific period specialist perspectives. The article is presented in this discursive format to reflect the differing opinions and approaches across an unusual multi-period project, in the spirit of multi-vocality and healthy debate.
