Query: Good novel, bad book

This Island Earth, the novel, is indeed different from the movie in the second half -- better, in my opinion, although less special-effects-driven. I don't remember the movie explaining the title, either; Jones is comparing Earth to the Pacific islands in World War II where the fighting washed back and forth, and the inhabitants were dragooned into helping build airstrips and such for either side. Here it's a war involving numberless galaxies (where the movie's was just between two planets).The novel is good, but the book is terrible. Pulpless.com's typesetters put in more typos than Raymond F. Jones could have made in a couple of centuries of writing. And the editors let it all slip by. But I don't believe there was any mass-market paperback, so this is the only game in town.
