The predecessor of these volumes was published in 1948 and was the fourth edition of the Projector Carbon Handbook also published by the National Carbon Company. That book contained information on the amount of screen illumination obtainable at that time with the combination of lamps, optical systems and carbons then available. These (the ones in this listing) bulletins came about almost a decade later as they were necessary due to the evolution of technology and offered new information for projectionists.
