This article discusses the post-excavation analysis and archiving of data generated by fieldwork undertaken at Heslington East near York in the UK. This project, stretching over two decades, involved two commercial companies and a student training and local community element, and recently concluded with a thematic publication (Roskams and Neal 2020). The article has twin objectives. First, on a theoretical level, it reflects on the complex challenges that arise when attempting to combine diverse stratigraphic, spatial and assemblage data from different sources to reach meaningful interpretations of an extensive, multi-period landscape. Second, on a practical level, it aims to act as an introduction to the project’s archives to make them accessible to future audiences, something that is essential if we are to enable any re-interpretation of the site.
