An interesting complaint about the packaging of Carl Schmitt translations here. The point is that these are slender volumes and could have been combined into something a little more worthwhile, which would also do away with the need for separate translator’s introduction and other apparatus. The initial focus of complaint is his Political Theology II, but that was at least a separate volume in German.
Perhaps as an antidote, there is a translation of an essay by Quentin Meillassoux, available free, here (via here).
