The official Hugo Awards records contradict the infobox years.

• The 2002 Hugo Awards list “Fast Times at Fairmont High” by Vernor Vinge under Best Novella, showing that Vinge won that category in 2002.
• The 2004 Hugo Awards list “The Cookie Monster” by Vernor Vinge under Best Novella, showing that he won again in 2004.
• The years shown in the article (2003 and 2005) are also contradicted by the official records for those years: the 2003 Hugo Awards list “Coraline” by Neil Gaiman as Best Novella, and the 2005 Hugo Awards list “The Concrete Jungle” by Charles Stross as Best Novella.

So the correct Best Novella Hugo years for Vinge are 2002 and 2004.

The official Hugo Awards listing for the work identifies “The Cookie Monster” as [Analog Oct 2003]. That means the novella was published in 2003 and then won the Hugo Award for Best Novella in 2004. The article’s parenthetical (2004) therefore misdates the work itself, likely confusing the publication year with the award year.
