Very useful time saving reference book, encapsulates the minutiae of characters, planets, species, aliens, robots, ships, etc from the 'saga', cannon and most especially the Expanded Universe of Star Wars novels, comics, games that have unraveled over 30 years. Last version was wonderful and exhaustive, and the update goes to 3 volumes. I pre-ordered it, and pub keeps expanding. No longer simply Sansweet, a team of historians penned the entries. ( )
