The table below gives access to details about the various setters, indexed by their pseudonyms. In some cases nothing is known about a setter other than the puzzles he or she produced. For reasons of privacy, real names are given only for setters who are deceased, whose information is already in the public domain, or who have given explicit approval. Setters who would like their personal information changed may contact or one of the vetters.

Cross-references: each setter has a primary entry, normally the first pseudonym used, with links to all other pseudonyms used (singly or jointly); these secondary entries have links back to the relevant primary one(s).
