Vincent F. Seyfried, The Long Island Rail Road: A Comprehensive History… (1961)
“ After the lapse of almost a hundred years very few original sources have survived; only a single printed prospectus for a bond issue remains from South Side days. It has been necessary, therefore, to rely heavily on the contemporary newspapers for a day-to-day account of the road. Every surviving newspaper that published in any locality served by the South Side R.R. has been systematically searched for material. ”
