The publisher very kindly let me have 3 copies of the 50th anniversary edition of ZMM published Tuesday last week.
I can confirm that as well as the new Foreword from Matt Crawford, this edition contains both the Author’s Introduction, the Afterword referring to Chris’s death and the Readers’s Guide, that were added at the 25th anniversary edition.
[Post Note: Posted a review of sorts here. And, I can confirm that the publisher HarperCollins page has links for purchase of the original US & Canada, English Language version, of the 50th Anniversary Edition, anywhere in the world.
