These measures appear in Indexes of Output Per Man-Hour, Selected Industries, 1939 and 1947-67 (BLS Bulletin 1612), December 1968. This report presents indexes for the corrugated and solid fiber boxes industry for the first time. Earlier reports in the paper and allied products group covered paper, paperboard, pulp, and building board mills."--Page iii.
