Engineering Textbooks - $18 (Lawrence)
I have six engineering textbooks that probably date back to the 1970's. Doubt that much has changed from these basic premises. Titles are: Manual of Steel Construction, Elementary Fluid Mechanics, Steel Design for Structural Engineers, Basic Science Concepts & Applications, Handbook - Ductile Iron Pipe-Cast Iron Pipe, Vector Mechanics for Engineers -Dynamics and Statics. All six are yours for $18.
