I’ve always wanted a full set of the Sphere paperbacks. They appeal to me because they aren’t available in the US. Of course to get all of them i’d have to also get the Futura Return of the Jedi because a Sphere books edition doesn’t exist. I do know they published Star Wars, Empire Strikes Back, Splinter of the Mind’s Eye and all 3 Han Solo novels.
I’m reading the Alan Dean Foster Novel of the first movie, Star Wars. My reading copy is Classic Star Wars a new hope, despite the added subtitle there haven’t been any textual changes. The abridged audiobook on the other hand was edited to bring it in line with the film and the then in development prequels, from Time Warner audiobooks and its disappointing. I don’t recommend the audio version read by Tony Roberts and abridged by John Whitman.
