Needs a PDF to show missing info from book

I know very little about this subject, so I enjoyed learning about the history. BUT there are constant references to tables and examples that are in the printed version but invisible to the listener of the audio version. This begs for a PDF that shows the visuals referred to in the book that aren't available on the audio..
