George H. Blakeley 
Dimensions, Weights and Properties of Special and Standard Structural Steel Shapes Manufactured by Bethlehem Steel Company [EPUB ebook] 

This early work on steel manufacturing is both expensive and hard to find in its first edition. It contains a comprehensive account of the specifications of products manufactured by the Bethlehem Steel Company. This is a fascinating work and is thoroughly recommended for anyone with an interest in the history of the steel industry. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
