Materials in Baker Library at the Harvard Graduate School of Business Administration for the study of labor relations have been recently increased by the gift of an unusually complete and well-organized collection from Thompson Products, Inc., of Cleveland. The equivalent of fifty thousand pages of documents, arranged chronologically and indexed, illustrating labor-management-government relations during the eventful years 1933 to 1948, are a welcome addition in themselves. But the fact that they illustrate the labor history of a company which has been in the forefront of the conflict over governmental interference in labor matters makes them of even greater interest to the student. In fact, had the company not been so labor-minded, the collection itself would probably not have existed.
