After being inspired by the webpages scattered throughout the Internet known loosely as 'The Anarchist Cookbook', I came across this, and I can only assume that the web-based versions are imitations of this - needless to say large amounts of it can be found freely on the Internet, but lacking the hand-drawn diagrams of the 'real McCoy'. However, this book should not be taken seriously. Not only is it at least 20 years old, but in over 15 publishings it has never been updated. William Powell, at the time, claimed he got his information from secret sources of his. Now, he is trying in vain to get this book taken out of print (some legal loophole or other prevents this from happening). This book contains hugely erroneous information, which, if taken seriously, may maim or kill you. Search the internet for 'anarchist cookbook error' and you will understand. And its author does not endorse it. It is a timeless classic, but is by no means the definitive 'be-all-and-end-all' of anarchist treachery. And now that the price has risen from £16 to £30 it hardly seems worthwhile.
