For Dummies is an extensive series of reference books which are intended to present non-intimidating guides for readers new to the various topics covered. Despite the title, their publisher has taken great pains to emphasize that the For Dummies books are not literally for dummies. The subtitle for every book is, "A Reference for the Rest of Us!". As of March 2013, over 1,800 For Dummies titles have been published. The series has been a worldwide success with editions in numerous languages.
