FAQ

The title is a reference to a fictional bureaucratic stipulation which embodies multiple forms of illogical and immoral reasoning. That the catch is named exposes the high level of absurdity in the novel, where bureaucratic nonsense has risen to a level at which even the catches are codified with numbers. A magazine excerpt from the novel was originally published as Catch-18, but Heller's agent, Candida Donadio, requested that it change the title of the novel so it would not be confused with another recently published World War II novel, Leon Uris's Mila 18. The number 18 has special meaning in Judaism (it means life in Gematria) and was relevant to early drafts of the novel which had a somewhat greater Jewish emphasis.

The title Catch-11 was suggested, with the duplicated 1 paralleling the repetition found in a number of character exchanges in the novel, but because of the release of the 1960 movie Ocean's Eleven this was also rejected. Catch-17 was also rejected, so as not to be confused with the World War II film Stalag 17, as well as Catch-14, apparently because the publisher did not feel that 14 was a "funny number". Eventually the title came to be Catch-22, which, like 11, has a duplicated digit, with the 2 also referring to a number of déjà vu-like events common in the novel.A 1950s/early 1960s anthology of war stories included a short version as "Catch-17".
