The Castle of the Otter is a collection of essays and other non-fiction by Gene Wolfe, related to his Book of the New Sun tetralogy.
 It takes its title from an incorrect announcement of Wolfe's final volume in "Locus".
 "The Citadel of the Autarch" was the actual name of the final work in the series.
 Wolfe liked the inaccurate title, though, and reused it as the name for a companion work of non-fiction essays and unused materials from the series (including an article about how "Otter" got its title).
"A Cabin on the Coast" is a science fiction / fantasy short story by Gene Wolfe, initially published in the February 1984 issue of The Magazine of Fantasy & Science Fiction and collected in "Endangered Species" (1989) and "The Best Of Gene Wolfe" (2009).
