The ...for dummies is a series of books that try to explain something very simply. The series was created in 1991 by Dan Gookin. The first book was about the computer operating system MS-DOS. Dan Gookin created the book, because in 1987 a person wanted a book that was simple and easy to read, as the person considered computer books to be dull at that time. After MS-DOS for dummies, came PC's for Dummies by Gookin, and Andy Rathbone. Other popular ...For Dummies books are The Internet for Dummies by John Levine, Carol Baroudi, and Margaret Levine Young, and Beginning Programming for Dummies by Wallace Wang.
