@oierem , compare the beginning of the ESB book to the ROTJ one. The ESB one has pages dedicated to pictures of GL's notes, transcriptions of them regarding the direction the overall saga would take in addition to the story of the episode being worked on... MoROTJ seems to have mostly just the outlines, story conferences, and drafts. It's possible GL resolved the Other and any circa-1980 thoughts about the overall saga without writing anything down, but if so that is quite different from the process behind the other films, no? EDIT. A lot of the story of ROTJ seems to be figured out in the story conferences instead of in notes. But the Other still is assigned without any thought process presented. And there is little about ROTJ's possible place in any Trilogy of Trilogies or how Leia became the Sister. Those seem like the kinds of things there might be notes about, but there isn't really anything (unless I missed it). So either GL didn't make any notes (which seems unlike how he did the other movies), the notes were lost (possible), or Rinzler, for whayever reason, wasn't allowed to show them.
