>In the November 1948 issue, Campbell published a letter to the editor by a reader named Richard A. Hoen that contained a detailed ranking of the contents of an issue "one year in the future". Campbell went along with the joke and contracted stories from most of the authors mentioned in the letter that would follow the Hoen's imaginary story titles. One of the best-known stories from that issue is "Gulf", by Heinlein. Other stories and articles were written by some of the most famous authors of the time: Asimov, Sturgeon, del Rey, van Vogt, de Camp, and the astronomer R. S. Richardson.
