The first one page dungeon contest received 113 entries. The contest organizers produced a formal "codex" of entries, available in two formats in PDF and print. The "deluxe" format included the entries plus commentary.
In addition, an informal "compendium" PDF of the entries circulated.
All of the submissions have been published as separate PDF documents on the contest site, and remain available for free download. In addition, individual authors have occasionally published their submission in various ways (occasionally with revisions).
