Celestial Recorders are the recorders who execute all records in duplicate, making an original spirit recording and a semimaterial counterpar.  Celestial Recorders are not created as such; they are ascendant seraphim from the local universes.  Custodians of Records serve as their Chiefs.  The corps of Celestial Recorders is of permanent assignment, they are mustered into these services for the distant future. 
Never has there been discovered a falsification in their records as they are being scrutinized by their exalted fellows from Uversa and by the Mighty Messengers, who certify to the correctness of the duplicates.  None have ever gone astray.  In Nebadon there are 75 senior or supervising recorders; on Uversa there are 8 millions.  Seraphim may attain Paradise through service as Celestial Recorders.  Celestial Recorders sponsor superuniverse seraphic record-keeping.  They are trained by Divine Counselors and Perfectors of Wisdom.  They appear in Uversa personality register.
