The entry says the book was published by HarperCollins in 1984, but HarperCollins did not exist yet: HarperCollins’ own corporate history says the modern-day company was founded in 1989. Contemporary 1984 sources also identify the book’s publisher as Little, Brown (U.S.) and Granada (U.K.), not HarperCollins. So the 1984 HarperCollins attribution is factually incorrect.

This bibliographic line combines incompatible publication details.

• WorldCat lists Disney's World: A Biography as an English, 1985 title published by Stein and Day, New York, 1985.
• The Scarborough House edition is a later one: the publisher page for the book shows Scarborough House with publication date October 1, 1990.
• That same official listing associates 9781589796560 with the digital/eBook version of the 1990 Scarborough House edition, not with a 1985 printing.

So the article’s wording incorrectly pairs Scarborough House and ISBN 9781589796560 with the year 1985.

This entry gives the Hearst Books edition a publication year of 1972, but contemporary catalog and review sources consistently date it to 1982.

• The George C. Marshall Foundation catalog lists Marshall, hero for our times / Leonard Mosley as a 1982 book from Hearst Books.
• Google Books also gives the title as Hearst Books, 1982.
• Open Library’s bibliographic record for the same OCLC-linked edition likewise dates it to 1982.

So the bibliography entry’s year is off by a decade.
