Do you know about a series of books that say they are “for dummies”? These American self-help books have been translated into more than thirty-nine languages including Chinese，Arabic，Russian，French，German，Greek and Spanish．

“Dummy”is a word for a stupid person．The dummies books are not really for stupid people．

They are designed to show people how to do something they may never have tried before，like painting a house or learning a language．The books all say in a funny way that they are for dummies，such as  World  History  for Dummies，Rabbits for Dummies，Chinese Cooking for Dummies，and Wedding Planning for Dummies．The first such book，DOS for Dummies，was published in 1991．It helped people learn how to use the DOS operating system for computers．Since then，more than one hundred fifty million dummies books have been sold．

The dummies．com website explains the idea behind the books．It says that they show that people can be taught to do anything．First they can make fun of ideas that are difficult to understand．Then they show how the information can be interesting and easy．The publishers（出版商）say that the books do not provide more information than necessary．They give readers just enough information to do what they want．They say that the dummies books give the best and easiest way to do something．And the books use simple and easy language．

There are more than one thousand different dummies books．A report in New York Times says that the top-selling dummies books are those that explain technology and personal finance（财经）．

The publishers say that the best-selling dummies books are those providing information many people need—like information about diseases，education and cooking．People interested in opera，car repair and wine can also find dummies books to help them．And there are even more dummies books to come．The publishers say that they publish about two hundred new dummies books every year．
