The Museum of Computer History collection includes artifacts from pre-computing to supercomputing, with a primary emphasis on post-WWII electronic computing. Although the museum is located in Mountain View, CA, a sampling of artifacts are provided online with promises to continue digitizing the collection. The website also provides a wealth of information for anyone researching computer history or simply curious about milestones in computer history. A key feature of the website is the timeline for the history of computing from 1945 to 1990, where visitors can click by year to view "illustrated descriptions of significant innovations in hardware and software technology," or search for a specific topic. A separate page provides a timeline for the history of the internet and another for the "microprocessor evolution." The document archive portion of the website contains various documents including history books, manuals, biographical and other historical materials.
