Ralph R. Shaw#Rapid Selector

The Rapid Selector was designed as a follow-up project of the Navy Comparators from 1938 by a development team led by Vannevar Bush. It was intended as a machine to manage large amounts of data and scientific work.

In Bush's draft documents have been reduced, stored on microfilm and machine-readable coded. The machine presented in 1940 was not the elegant, inexpensive Memex, had described the Bush years earlier, but it was patented in 1942 and used during the 1940s and 1950s in the Secret Service, and the American librarianship.
