President Lyndon Baines Johnson’s presidential library has holdings relevant to the study of federal education policy history, such as these Douglass Cater oral histories. Cater served as special assistant to the President from 1964 to 1968, and offered comments on the politics of education at the time of enactment of the Elementary and Secondary Education Act of 1965.
Other oral histories may be found here, and finding aides for Lyndon Johnson’s papers are located here. The photograph above came from the library’s photo archive.
