Now in paperback -- the only comprehensive introduction to the structure and context of archaeology in Britain with chapters on legislation, planning policy and preservation.
As dry a read as it is, for a book published in the early 90s there is still a lot relevant to today - certainly if you want to understand the finer details of the history of archaeological management and how we got where we are today this is a great foundation.
As someone learning now, this is a good way to get information on what those with decades of experience have long been practising and building upon.
It is also a good launching point for researching what has changed since the 90s, and which of the key talking points in this book have been addressed to some degree now (creation of computerised national archives, public community involvement, diversity in the workforce, and more).
