The Guardian Plates
In the year 2010, a team of data-conservator Urantia Book readers scanned a copy of the 1955 First Printing of The Urantia Book into a set of computer files. The files thus obtained are in the public domain. The master copies of these images are called "The Guardian Plates," and are perpetually maintained unchanged and copies made publicly available around the world by a small group of conservators called "The Guardian Plates Conservatorium."
