Lobster: The Journal of Parapolitics was started in 1983 by Robin Ramsay and Stephen Dorril, two conspiracy enthusiasts who weren't actually nuts and believed in proper research. The magazine primarily covered the activities of the British security and intelligence services and what they term 'parapolitics'. They've had a brochure website for a while with some sample articles, but starting from the current issue the full journal will be free online (PDF download). The pair had a falling-out some time ago and have gone their separate ways. On his personal site Dorril, now also the author of a well-received study of Mosley and the Blackshirts, offers early back issues of the magazine for free download too.

It highlights "four interconnected drivers of global insecurity: climate change; competition over natural resources; global militarism; and poverty and marginalisation. Prof. Paul Rogers makes the case for a rethink of the security paradigm.
