I also find it interesting that the words "Star Wars" don't actually appear anywhere on the cover of the original edition of the books but does mention the "Adventures of Luke Skywalker." I think you mentioned that in Secret History as I recall though.

Well that makes sense. Until ESB came out, no one knew that the whole series was titled "Star Wars". "Star Wars" was a movie that came out in 1977, and "Splinter of the Mind's Eye" was its book-sequel.
