INTRODUCTION

For at least ten years, there has been much discussion within the field, referred to by this volume, of the relationship between ‘Industrial Archaeology’, ‘Post-Medieval Archaeology’ and ‘Historical Archaeology’. The discussion incorporates diff erent types of material, diff erent dates, and diff erent research agendas, and it doesn't appear to be near to resolution. Perhaps, rather than trying to find some unifying thread between these diff erent fields, it is of more use to archaeology, certainly in terms of strengthening archaeological theory and practice, to work to establish them as diff erent, or even opposed, ways of seeing. By this I mean that each of the above disciplines can assuredly bring a diff erent focus, diff erent body of theory and historical development and diff erent ways of working to the wider field without any need to integrate them. The creation of all-encompassing research agendas, something that would be an inevitable result of any attempt to answer the question of what the above sub-fields actually are and how they relate to each other, should be seen as secondary in importance to the need to be comfortable and confident withthe way we work; comfortable withpeople working in diff erent ways to ourselves; and confident that other ways of working primarily serve to challenge and strengthen Archaeology rather than posing a threat.
