The Mathematical Tables Project was one of the largest and most sophisticated computing organizations that operated prior to the invention of the digital electronic computer. Begun in 1938 as a project of the Works Progress Administration(WPA), it employed 450 out-of-work clerks to tabulate higher mathematical functions, such as exponential functions, logarithms, trigonometric functions. These tables eventually filled 28 volumes, which were published by Columbia University Press.
