The Haydock name became so popular and so closely associated with English Catholic Bibles in the 19th century that at least one publisher ca. 1886 "pirated" it for an edition that included only the standard Challoner annotations by adding the statement to the spine of his edition, "Challoner's Notes and Other Important Features of the Haydock Bible". During the 1940s and 1950s, some "pocket" editions of the Catholic New Testament (usually referred to as the Rheims Testament when published separately) appeared, erroneously crediting "Canon Haydock" with the annotations.
