"A Marsh and a Gasworks" was written by John Marriott with support from his WEA students. It is usually listed under the authorship of "Newham History Workshop", which I don't think exists any more. Its publication in 1986 was part of the West Ham centenary celebrations that also included republishing the West Ham volume of the Victoria County History.
I met John a few years ago, at the launch for the book on the Silvertown Explosion, and mentioned either reprinting or creating a web-based version. He was all in favour but thought there would be difficulties with Newham Council in getting permission to use their photographs again, as the borough had changed its charging policy.
Don't wait to buy second-hand from eBay. Use ABEbooks http://www.abebooks.co.uk
where there are 7 copies listed today, starting at £12 for an ex-library copy.
Incidentally, the tile comes from a remark by one of the daughters of one of the rich developers of the south of the borough, who said to a friend "Father has gone mad, and bought a marsh and a gasworks" (or words similar, I don't have the book to hand just now).
You can check John Marriott at http://www.uel.ac.uk/hss/staff/john-marriot/index.htm
which states he has written a history of East London, due to appear this year. Hopefully there will be a good local book launch and we will all be able to get our copies signed.
