The "Dome Cookbook of Geodesic Geometry" by David Kruschke is no longer available at Half Priced Books, or any other source I can find on the web, including Amazon.
From what I understand, this book is the information source for Mr. Kruschke's flat bottom 3v dome, as well as other geodesic structures with a flat bottom that he designed.
It would really help all of us if someone would scan this book into a PDF form, to preserve it for the future, much like DomeBook2 by Lloyd Kahn has been preserved in electronic format.
It appears the "Dome Cookbook of Geodesic Geometry" is no longer under copyright protection, as it was copyrighted in 1975.
Under US Copyright law, any work copyrighted before 1978 has a duration of 28 years - meaning that the 1975 copyright expired in 2003.
And it does not show up on the US Patent and Trade Office Copyright database as being protected by a copyright:
If I knew Mr. Kruschke or his family, I would contact them for their input. But at this point, I cannot see how they would be offended.
If this document is never scanned into electronic format, the existing paper copies will someday be lost or destroyed, and the genius of David Kruschke will be forgotten.
If this document is put into electronic format, and put on the internet, it could last for a very long time.
Mr. Kruschke has a very good solution for building a 3v dome. Many dome manufacturers are using this information, with very little credit given to David Kruschke.
I think it would be an honor to Mr. Kruschke to do this for him. But if someone could contact him or his family first and receive their blessing for this project, that would be perfect.
