Trivia

 * In the original The Binding of Isaac, due to a typing error this item was called "Monster Manuel". This has been corrected for Rebirth.
 * Monster Manual may sometimes display the misspelled name when picked up.
 * Monster Manual is a direct reference to Dungeons & Dragons. Its appearance in the game closely resembles the Advanced Dungeons & Dragons First Edition Monster Manual.
 * The item being in the Devil Room pool is likely a reference to the moral panic surrounding the game in the 1980s.
