The Engineering Experiment Station (EES) contracted with government agencies, technical societies, associations, and industries for research of a general or special nature. The results of the experiments were mostly made available for the public good. There were three categories of outputs by the EES: bulletins, technical papers, and circulars. This collection consists of all 35 bulletins, with a date range of 1923 to 1952. The EES was discontinued in 1953.
