Jack:
My question is this:
Is there a more economical way to produce and distribute the same data, yet still retain control of the intellectual content?
You seem to embrace technology and I wonder if you could simply make the same data available using a secure website that users pay a one time or annual fee for access that incorporates a mobile app also accessible with smartphones?
Then you control all access, content, have the hit ratios of users, etc.. You can trademark/water stamp images, pay homeage to origin of photos or contributors, easily add/delete or update the content and values, if included. You could also include the air meter and other data to drive additional revenues. Links to and from websites like this mightdrive additional revenues.
Making your content digital secures it from physical harm such as theft,fire, floods, hurricanes, tornadoes etc and preserves it for the future collectors hobbyists...
I am sure there are far more investors, code writers, computer software and web designers that would be willing to jump on board to this format or perhaps offer to do the work under a limited partnership over a single print book that becomes outdated rapidly. It would be a real investment that has real value as it evolves and would continue your legacy of amazing research. Possibly creating a far more valuable tangible asset that you could leave to your family or sell when you are ready to hang up your hat.
These are only my thoughts & questions. Please know I hold you and your work in the highest regards and thank you for all your time, effort, knowledge, research, books & posts here.
Best wishes and God Bless;
