Be warned: lulu.com offers a paperbound volume “edited and published by Christopher D. Seely” that contains both New Libertarian Manifesto by Samuel Edward Konkin III and my own Agorist Class Theory. I purchased a copy and can report that it is incomplete and filled with typographical problems. For one thing, within the first page of NLM, I found entire lines and at least one paragraph missing; I ventured no further. For another, my introduction to Agorist Class Theory, explaining the source of the chapbook’s material, is missing entirely.
The definitive text of SEK3's New Libertarian Manifesto remains the 25th Anniversary Edition published last year by Victor Koman and available from KoPubCo. Most online versions seem to offer problems. The KoPubCo edition, by the way, also features valuable critiques of NLM by Murray Rothbard and Robert LeFevre. As for Agorist Class Theory, it’s offered at lulu.com in a standalone edition, and Brad Spangler has a reliable free downloadable PDF available.
