New York and London: John Wiley & Sons, Inc. January 1947. Later printing. xxiii. [1-blank], 772 pages. 8vo. Publisher's blue cloth with silver spine lettering and logo stamped in blind on front board. Spine sunned. Stamp of "Jay W. Forrester Mar 12 1947" on bottom page edge and very lightly on the fore-edges. A sound copy noting corners bumped and extremities rubbed. Dampstaining to rear boards. Very Good. Cloth. 
The third book in a new series by MIT designed to overhaul the curriculum related to Electrical Engineering. Other volumes were "Electric Circuits" and "Magnetic Circuits and Transformes". Intended as an introductory course applicable regardless of a student's eventual specialization. It apparently appeared on Forrester's shelf on Mar 12, 1947, mere months before Bell Labs demonstrated the transistor (Dec. 23, 1947).
Relevant to Forrester's work toward magnetic core memory and a nice ownership as a result.
"Jay Forrester was born near Anselmo, Nebraska, in 1918. He holds a B.S.. in electrical engineering from the University of Nebraska (1939) and an M.S. from MIT (1945). While leading the MIT Whirlwind computer project (1947-1953), Forrester developed the "coincident-current" magnetic core memory system, the first reliable, high-speed random access memory for digital computers. This invention was of monumental importance to the further advancement of digital computers and was used for main computer memory in most computers into the 1970s." (computer history museum bio)
