The Engineering Magazine - an International Review, Volume XXI (April to September 1901). Bound volume of six complete monthly issues.

Noteworthy for a large feature article on the Mechanical and Electrical Features of the 1901 Pan American Exposition, Buffalo, NY, written by prominent engineer William S. Aldrich. It includes dense technical text, photographs, and schematics focusing on the fair's cutting-edge technologies:

• The Electric Tower: Detailed analysis and photo plates of the fair's iconic centerpiece, showcasing how it was powered and illuminated by the newly harnessed alternating current from Niagara Falls.
• The Electricity Building & Machinery: Deep-dive illustrations of the interior exhibits, focusing on new generators, motors, and high-voltage electrical distribution panels.
• Transportation Exhibits: Detailed looks at the massive locomotives, railway technology, and newly emerging electric mining locomotives on display.
• Advanced Engineering Systems: Blueprints and descriptions of the fair's infrastructure, including electric-driven air pumps, massive water condensers, and the engineering behind the Grand Canal fountains.

In addition, Volume XXI features deeply technical essays, case studies, and charts organized across several fundamental tracks:

• The Rise of Scientific Management: This specific volume is rich with early foundational texts regarding "shop efficiency," standardized labor, and materials management that would later evolve into Fordism and Taylorism.
• International Technical Competition: Multiple articles focus heavily on "Modern American Competition" and the comparison between American and British industrial capacity—specifically highlighting rolling mills, metallurgy, and the development of international free trade.
• Civil & Structural Engineering: Includes early practical studies of reinforced concrete in practice (a cutting-edge construction technology in 1901) and the expansion of large-scale municipal water systems and power plants.
• Transportation Infrastructure: Focuses heavily on rapid transit developments, heavy railway mechanics, and locomotive advancements designed to move industrial goods across continents.
• Mining and Military Engineering: Contains rare breakdowns of global resource distribution—such as Australian iron resources—and the mechanics of modern artillery systems
