A note about the serial (Gravy Planet): book versions - titled The Space Merchant - include the note "A condensed version of this novel appeared in Galaxy magazine under the title Gravy Planet." I've compared the text and don't find them that different, with some events changing order in the last book chapter. Ending the book here probably makes sense dramatically: puzzles solved, reconciliatons made, new beginnings to look forward to, and so on. But the magazine has 2 chapters that are NOT in the book! Chapters 20 and 21 (pp 149-159 in the August issue) take place on Venus, whereas the book ends with them just about to arrive on Venus. If you want to find out what the original ending was - you'll have to get a set of the original magazines (and decide for yourself whether the last chapters were best left off or not.)
