Noland has approximately 3500 GM diagrams show parts, numbers, and manufacturing specifications. Most of the diagrams are 24in x 36in. I scanned these diagrams by posting the diagrams on the wall and taking a very high resolution picture in RAW format. Converting these pictures into a usable format is very time consuming, and I have only converted about 800 of the pictures so far. The quality of the pictures is pretty good. A meaningful percent of the diagrams have faded or discolored significantly, and are very hard to read.
