Excerpt from "The Library Services and Construction Act" by John C. Frantz, Published in the ALA Bulletin Vol. 60, No. 2, Federal Librrary Legislation, Programs, and Services. (February 1966), pp. 149-152
From 1957 to 1964 the rural Library Services Act had conspicuous success in extending and improving public library services to more than 40 million persons living in places with less than 10,000 population.
Excerpt from "LSA and LSCA, 1956-1973: A Legislative History" by James W. Fry. Library Trends, July 1975.
A U. S. Office of Education study conducted in 1956 revealed that 26 million rural residents were without any public library service and that more than 300 rural counties had no public library within their borders. The study also reported that an additional 50 million rural residents had only inadequate service. The Library Services Act of 1956 was a significant step forward in providing improved library services for these neglected areas.
U.S. population in 1956: 168,903,031, which means that 15% of U.S. residents were without library services and another 30% had access to inadequate service.
As this column graph demonstrates, bookmobile service is slowly on the wane. There were 874 bookmobiles in operation in 2001, 734 in 2010. And the news isn't getting any better. [And here.]
According to the Public Library Service Data, there were 8 bookmobiles in operation in Wisconsin in 2011.

In my first public library job as Head of Extension Services at the Oshkosh Public Library, I supervised the operation of two bookmobiles, one that operated within the city, the other in Winnebago County. This era of the library's history ended in 2007.
