About half of these were original to the 1950 edition - including many short bridge-passages or vignettes (marked "{br}".) In THE RAY BRADBURY COMPANION (1975), W. F. Nolan states that the "bridge-passages" have NO relationship to stories of the same title appearing elsewhere. The rest first appeared from 1946 to 1950 - in MacLean's, Arkham Sampler, Thrilling Wonder Stories, Planet Stories, Super-Science, Charm, Colliers. British editions have often had slight variations of the contents (1 or 2 stories added/omitted.)

The lineup of stories for this book has "evolved" since its original 1950 edition, with British variants having one or more stories omitted (and substituting others not in the 1950 lineup.) American editions eventually included the stories added/substituted by British versions ("The Fire Balloons" and "The Wilderness" were both included in the standard lineup by 1973.) This 2001 edition adds a new preface by K. S. Robinson to the contents of the 1997 Avon edition - which had "been updated and revised" (dates of the stories have been pushed back 31 years.) That 1997 lineup drops "Way in the Middle of the Air". With the new introductions and revisions this is definitely not a facsimilie reprint, but it hearkens back to the original 1950 hardcover by using the same cover art.
