For Dummies is an extensive series of instructional reference books that strive to present non-intimidating guides for readers new to the various topics covered. The series has been a worldwide success, with editions in numerous languages. The books are an example of a media franchise, consistently sporting a distinctive cover—usually yellow and black with a triangular-headed cartoon figure known as the "Dummies Man", and an informal, blackboard-style logo. Prose is simple and direct. Bold icons—such as a piece of string tied around an index finger—indicate particularly important passages. Source: Wikipedia (en)
