The mission of the Computer History Museum is to preserve and present for posterity the artifacts and stories of the information age. As such, the Museum plays a unique role in the history of the computing revolution and its worldwide impact on the human experience.
The Computer History Museum maintains the world's largest collection of materials related to the history of computers, including hardware, software, documentation, ephemera, and media. With over 25 years of collecting efforts, the Museum seeks to preserve a comprehensive view of computing history, one that includes the machines, the software, the business and competitive environments, personal recollections, and the social implications of humankind's most important invention, the computer. The Museum does not pursue any ideological "party line" with respect to computers - past, present, or future - in either its selection of objects for inclusion in the collection nor in its approach to computer history. This approach is one of the many factors that have made the Computer History Museum a trusted and globally recognized source on computer history.
