Dot, I think the Communist bookfair would be too different than the Marxist bookfair in that there are anarcho-communists and other anarchists who view their ideas as being in line with the whole Libertarian Communism would table at the bookfair. I don't agree with the ideas, but I could see that having some connection. Whereas the Marxist bookfair would be more interesting to me, because the whole philosophy or religion of Marxism is based entirely around the mindset of one individual. Communism in theory can be less bound to one individual thinker. Also, Marxism and Anarchism should have a historical antagonism starting with Marx vs. Stirner and Marx vs. Bakunin. From my perspective, a Marxist bookfair would be founded in the idea of Marx as the sole or primary source for understanding how life is structured. This goes along with Ingrate's comment on most (all ?) Marxists not being interested in dialogue and ideas. If someone doesn't think Marx is a great thinker or the greatest thinker in the history of the world (or at least, since the beginning of the class struggle for them), a Marxist bookfair is largely null and void.
