@KettermanHillCoop - I too struggled with the digital versions of the books. Bought the digital content for like $2.00, downloaded free PDF files, etc. finally got way too confused and aggravated so decided to actually buy a hard copy of the 1924 version (the green cover).
I can totally say it was worth it - if nothing else for my sanity. The hard copy seems much clearer and easy to understand and the illustrations and diagrams are more detailed.
