Blackwell issued a 2nd edition of The Great Arch in 1991, six years after the original publication, for which Philip Corrigan and I wrote a postscript discussing new work on English state formation published since 1985, and responding to various reviews of the book.  Both entailed some clarification and extension of its arguments. The 2nd edition had a very small print-run and soon went out of print, so this text is little known.

The excellent cover illustration is from Lyubov Popova’s set for The Earth in Turmoil (1923).  I have posted a downloadable scan of the postscript here for anyone interested.

There was also a Spanish translation of the Introduction and Afterthoughts sections of The Great Arch, in Antropología del Estado: Dominación y prácticas contestatarias en América Latina, ed. María L. Lagos and Pamela Calla, Cuaderno de Futuro Nº 23, La Paz (Bolivia): Hernando Calla, 2007, pp. 39-116.  A pdf can be downloaded free here.
